- apache 2.2
php 5.3.28
ram 20g
- 16 cores
in apache have configured 40 domains, following characteristics:
<virtualhost *:80> servername domain.com logformat "%{x-forwarded-for}i %l %u %t \"%r\" %>s %b \"%{referer}i\" \"%{user-agent}i\" **%t/%d**" combined_t errorlog "|/usr/apache2/2.2/bin/rotatelogs /opt/avv2002_data/logs/domain_err.%y%m%d 86400" customlog "|/usr/apache2/2.2/bin/rotatelogs /opt/avv2002_data/logs/domain_log.%y%m%d 86400" combined_t loglevel info documentroot "/opt/www/apache/joomla/sites/" directoryindex index.htm index.html index.php <directory "/opt/www/apache/joomla/sites/"> options -indexes followsymlinks includes multiviews allowoverride rewriteengine on rewritecond %{request_filename} -s [or] rewritecond %{request_filename} -l [or] rewritecond %{request_filename} -d rewriterule ^.*$ - [nc,l] rewriterule ^.*$ index.html [nc,l] </directory> </virtualhost> a few days ago development uploaded new application in php , server started problems ram , cpu, looking bit found following:
too many process, children , time_wait.
example:
use swap.
extract swap pmap
swap: 212276 bytes pid: 23158

i thinking of profiler of php, see domain taking longer
any idea else should check?
you have reached maximum number of workers, need increase it. have posted guide on how increase max number of apache workers on whm, in case, need manually in configuration file of apache (change maxclients 1024).
now question is, why did reach maximum number of workers, because real traffic, or because of else?
my advice check apache logs (i don't know structure on solaris, last time worked on in 2004) , see website having traffic (it traffic biggest log). should analyze traffic: real traffic? bot traffic? if bot traffic, legitimate bot traffic (if not, should block illegitimate bots)?
if real traffic, have lot of 404s? if yes, need address 404s - because each 404 need worker in joomla instance.
