Apache hangs without traffic

[comex]

Hi, I"m also facing the same issue, but on a VM with CentOs5.6 and ISPConfig3.

[Thesee]

Did you solved?
I migrated all the production vhost on a second server, all is working great.
Then I re-installed centos but without the required software setup for ispconfig3
All was working good.
Then i reinstalled centos with the software required for ispconfig 3:
apache hangs without traffic!!!

Probably is related to some software configuration (i followed the how-to guide) but i dont know what to check.

Regards.

Which errors do you get in the apache error.log file?

[Thesee]

here the lines before crash

[error] server reached MaxClients setting, consider raising the MaxClients setting

This happen because httpd hangs and then all requests are queued, within minutes the queue becomes full

httpd config

Timeout 150
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 8
<IfModule prefork.c>
    StartServers          30
    MinSpareServers       10
    MaxSpareServers      20
    ServerLimit		100
    MaxClients          100
    MaxRequestsPerChild   8000
</IfModule>

It might be that perl modules are missing on your server which causes the apache vhost logging /vlogger) to fail. Please search the error log if there are any errors for vlogger inside.

You can also run the command:

vlogger -v

to see if you get any errors.

vlogger -v

vlogger -v

no vlogger entries on log files, seems is working good.

any clue?

Ok. Just to be absolutely sure that not vlogger is causing this, edit the ispconfig.vhost file (which is in the sites-available folder in the /etc/httpd config folder) and comment out the custom_log directive and then restart apache.

Hi Till,
on ispconfig.vhost file the custom_log directive is already commented out.

there is an ispconfig.conf file with

CustomLog "| /usr/local/ispconfig/server/scripts/vlogger -s access.log -t \"%Y%m%d-access.log\" -d \"/etc/vlogger-dbi.conf\" /var/log/ispconfig/httpd" combined_ispconfig

maybe you was referring to this file?
should i also comment out this?

[till]

you are right, i meant that file please comenr it out in ispconfig.conf

[Thesee]

Ok commented out!

#CustomLog "| /usr/local/isp.....

httpd restarted

I'll let you know
