Using Apache 2.0.52 + PHP 4.3.10 on Linux (Fedora Core 2), I get this
error message when accesing my PHP page:
---------------
Service Unavailable - Zero size object
The server is temporarily unable to service your request. Please try
again later.
Reference #15.21eaaad4.1173400585.294a7ed8
---------------
I fixed it by restarting Apache, but I'd like to know the reason of this error. Does anybody have any experience with this issue?
I have uploaded typo files to /etc/rails_apps/typo and setup mysql database user password. When I visit the domain at [url]typo I get a 503 / Service Temporarily Unavailable error message.
I am using windows 2008 R2 64 bit O.S, I downloaded httpd-2.4.10-win64-VC11 and tomcat-connectors-1.2.39-windows-x86_64-httpd-2.4.x and I created 3 tomcat workers and then I configured workers.properties and httpd.conf.
After complete setup when i tried using
http://localhost then
I got It works! message (looks everything is fine).
and then I have deployed my sample web application I tried to access the same application then using
http://localhost/SampleCluster
I am getting
503 service not available.
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Suddenly my server stop to accept mail from outside. Here you have the logs of mail.info
Feb 20 14:26:02 xxx postfix/smtpd[5581]: 17098E1CCB: milter-reject: DATA from mail2.email-o-matic.com[217.116.24.xxx]: 451 4.7.1 Service unavailable - try again later; from=<empresas@xxx.es> to=<whatever@whatwever.es> proto=ESMTP helo=<mail2.email-o-matic.com>
It seems it is a milter problem as in the line I can read "milter-reject"
Also I have a lot of lines like this:
Feb 20 14:27:34 dv2 greylisting filter[9152]: Starting greylisting filter... Feb 20 14:27:36 dv2 greylisting filter[9154]: Starting greylisting filter... Feb 20 14:27:37 dv2 greylisting filter[9165]: Starting greylisting filter...
I can go to control panel and stop plesk milter but I see these lines on mail.info
Feb 20 14:30:04 xxx postfix/smtpd[8845]: warning: connect to Milter service inet:127.0.0.1:12768: Connection refused
And 4.7.1 still there
Feb 20 14:30:03 xxx postfix/smtpd[7289]: NOQUEUE: milter-reject: CONNECT from 223.179.15.xx.dynamic.jazztel.es[37.15.179.xx]: 451 4.7.1 Service unavailable - try again later; proto=SMTP
Maybe is a port (12768) connection error? How I can test that port?
This KB article does not solve anything as the load of the server is 0.1-0.5 [URL] ....
A temporal fix is to edit /etc/postfix/main.cf file comment these two lines:
We have just installed the plesk version 12. All the installation completed without errors . then we restarted the server . and when we tried to open the plesk through the desktop shortcut we get the error " HTTP Error 503. The service is unavailable."
We have tried the following links fix HTTP , kb6735 .
I'm running a CentOS 6 server with Plesk 11.0.9 installed. It's only being used for dev purposes with only a couple vhosts running on it. All of the vhosts are using PHP - there are a few WordPress sites and Zend Framework 2 applications running. Up until a few months ago it was also running a high traffic WordPress site, but that's no longer the case.
This server has been running without problems for over a year. A few days ago I first started noticing 503 errors (Service Temporarily Unavailable) on accessing one of the vhosts from the web browser.
I logged on through ssh and noticed the load was a bit higher than I expected (nothing crazy though). All other vhosts using PHP also gave me the same error. The only vhost that was working normal was a Ruby on Rails app (Redmine).
I also did a netstat -napt and noticed many connections from two or three IP addresses. I checked their geographical location and after blocking them through iptables the problem seemed to have gone away.
Now it's a few days later and the same problem started popping up. I checked again through netstat and noticed that again a whole bunch of connections from only a handful of IP addresses were connected to Apache.
When I was digging deeper I noticed that some of those IP addresses were what looks to me like other servers (at least they're running Apache). I'm suspecting they are hacked servers and they're trying to use my server to send spam or some other type of evil.
I just blocked those new IP addresses in iptables and that seemed to have solved the problem for now again, but I want to solve the root of the problem.
So my questions are: 1) How can I find out to what vhost those clients are connected? 2) Why does Apache stop working with not that many client connections, when it used to serve thousands of visitors at the same time when that big site was still running on this server? 3) What could they possibly be using my server for? The first time it happened I thought that they found some leaking WordPress plugin to use to spam people, but today I checked and there's barely anything in the mail queue.
I activated greylisting on my mailserver and took a look in the logfiles.
The mail are temporary rejected with the following log message / statuscode:
451 4.7.1 Service unavailable - try again later;
Mails from my server to other servers are greylisted with messages like: 451 4.7.1 message delayed, see http://www.greylisting.org ; 452 Greylisted. Please try again after some time. 451 4.7.1 <E-MAIL-ADRESSE>: Sender address rejected: Greylisting in action. Please try again later.
Is it possible to change this log message at my server?
Every now and then I will attempt to load my Plesk 12, CentOS6 Website, and receive the following error:
503, Service Temporarily Unavailable.
It requires a restart of nginx and apache in order to remove the error. It then can come back in a week, or in a few hours. Its completely random. I also can't find anything in the logs.
This started happening after I enabled backups, then later disabled backups because of problems with my backup server. However this does not occur when my scheduled backup was.
All genuine emails are making it through fine - barring one or two domains, which fail with postfix/cleanup[5184]: warning: milter inet:127.0.0.1:12768: can't read SMFIC_BODYEOB reply packet header: Connection timed out
postfix/cleanup[5184]: 5082A22A8E: milter-reject: END-OF-MESSAGE from XX-XX-202-76.dsl.in-addr.zen.co.uk[XX.XX.202.76]: 4.7.1 Service unavailable - try again later; from=<newsalert@financialexpress.net> to=<nameremoved@domain.co.uk> proto=ESMTP helo=<mailrelayname.co.uk>
Since the last update I am having constant troubles with email accounts when sending or replying to email messages.
This is the message I am getting:-
"error sending your message: Service unavailable - try again later"​

One of our resellers has an account.. When looking into cpanel, it says that that account is using 3300megs. When we go into the ftp of that account, in reality it is only using 1.3megs. This is a huge difference! Most of folders are empty. We are using the latest version of WHM and Cpanel.

I run plesk 12.00.18#7 and i have upgrade from 11.5.30 ....
after i migrate from Plesk 8.6 to Plesk 11.5 some of my Domains have trouble.When I want to open one of the Domain i become this error here: Internal error: Unable to load object of type Account with id=340: Account: unable to select: no such row in the table
In the databases i found some of errors here:

I have already do this here: [URL] .... and reconfigure all my domains again, but the issue dont fix.
In Cpanel, If i click on Apache Status it tells me aload of website that have been visited recently, under the vhost column. It shows this but sometimes under those it shows aload of (unavailable). Why is this. Is this normal?
Some of my Linux(WHM/Cpanel) hosted domains have a weird problem. They randomly become unavailable to me for periods of half hour to 2 hours. During this time I get a server not found error and I cannot access the domains through FTP either. However if I use a proxy or try to reach the domain through another server using RDC I am able to reach it.
One particular server I have out of a few (same data center / network) is acting up network wise. The server load is minimal, so its not that. The NOC confirmed no network issues either, which makes sense since its one server out of about 4 that have this issue. All have the same exact specs, o/s, Cpanel, etc.

I have a plesk 11.0.9 on a windows server 2008 R2 which has MailEnable. One of my customers faced a problem to send emails from one of his local mailboxes to another of his local mailboxes! He got this error:Your message did not reach some or all of the intended recipients.The following recipient(s) cannot be reached.Server error: '550 Requested action not taken: mailbox unavailable or not local'
But we are sure the recipient mailboxes exist and work fine!I checked this link: URL....It dosen't work for this case.
I've just recently installed Plesk Panel 11.5. Previously I was using a basic IIS Mail Server with the current server allowed to relay messages for my Web Sites.After installing Plesk, I went to Tools & Settings -> Server-Wide Mail Settings. In there, I have relaying set to Authorization is required (SMTP) and for the relay access I have the following 3 entries:
127.0.0.1/32 ::1/128 <My Servers IP>/32
Whenever one of my sites tries to use this server now to send out mail, I keep getting the following error:Mailbox unavailable. The server response was: Requested action not taken: mailbox unavailable or not local...I've been struggling with this issue for weeks now and have read all the documentation and forum posts I could think of, I've restarted the server, I've run C:Program FilesSWsoftPleskadminin>mchk --all --fix=all
The e-mail accounts that I'm using to send mail from has nothing to do with this server and it's domains, I'm just trying to set the mail server to start sending mails like my IIS server used to.I've found the setting to Open Relay on the server and have activated it, yet whenever one of the websites attempts to send a mail, the same response is received.Mailbox unavailable. The server response was: Requested action not taken: mailbox unavailable or not local.
Rapidly growing error logs showing the same message
