Long-live Apache Processes

I have some problems with apache.

As you can see below, long-live httpd processes use a lot of CPU / Ram.
Usually this processes caused high LA - 8-12.

Code:
%CPU CPU NI S TIME COMMAND
0.2 - 0 S 00:00:27 nginx: worker process
0.3 - 0 S 00:00:29 nginx: worker process
0.3 - 0 S 00:00:30 nginx: worker process
3.3 - 0 S 00:04:09 /usr/local/apache/bin/httpd -k start -DSSL
