Auto Restart of Services

[LinuxFreaky]

Where and how does WHM monitor and automatically restart services that die? I've been having problems recently with one of my servers. Httpd would die every couple of days and WHM won't know a thing about it. In the sevices status page everything is green, and Cpanel doesn't automatically restart it either.

hi guys

cpanel does restart the service automatically if it fails. the checkservd will constantly check all the services - apache, exim, bind, mysql, interchange, proftpd, syslogd, webmail etc.

Well, chkservd seems to be ignoring my apache too. I've had to manually restart Apache several times now (its gone from the ps list) and chkservd/WHM didn't notice.

I had mod_gzip installed, so I've removed that to see if it still keeps hanging.

I have been having the exact same problem. Apache and exim fail in the middle of the night. WHM checks out fine, so its not till I get to my works station and have a load of angry customers that its restarted. Has anyone submitted a bug for this yet?

1) Look in /etc/resolv.conf & /etc/hosts and make sure they are correct; Services fail continuously if those files are not setup correctly

2) So many users or low system resources like RAM & CPU Speed
In WHM -& Security -& Modify Apache Memory Usage Limit

what exactly should be in those 2 files? Just curious, because I believe mine are set up correctly, but I would like to be sure.

/etc/hosts :

# Do not remove the following line, or various programs
# That requires network functionality will fail.
127.0.0.1 localhost.localdomain localhost
Server-IP domain.com Short-Host-Name

/etc/resolv.conf :

domain domain.com
search domain.com
nameserver IP-of-ns1.domain.com
nameserver IP-of-ns2.domain.com
# you can have additional nameservers here

Also check your DNS settings (nameservers & hostname)

Why you don't use this to free up some resources

It's not related to the hosts or the resolv.conf files.

This is most likely a bug in the checkserv daemon, as it is effecting my server as well.

I spoke with venturesonline's helpdesk, and they've stated that the checkserv daemon not paying any attention to a dead apache is becoming very common across their dedicated and virtual servers.

I'm working on a shell script to run via cron to help restart apache until such time as the checkserv daemon is corrected.

If this is a bug why the others haven't any? Substantial servers are running Cpanel, also we haven't had such error with our servers (P4 1.6GHz to 2Ghz with 256MB to 2GB RAM)
LinuxFreaky also wrote that they have the problem just with one of their servers not all of them,
There will be 3 possible choices for root of such trouble
1) System Resources
2) invalid configuration
3) Bug (you selected this but why it's not so populated and why should not to control both above choices first)

[indiboi]

Cpanel bugs are almost always sporadic in nature.

There's no point in arguing over it though. Server works fine, cpanel updates, server no longer works fine.

Configuration is fine prior to and after cpanel update

System resources have never been an issue before.

A problem with the checkserv daemon is the logical conclusion.

You'd never notice this unless apache did fail, and realistically that isn't very often.

[indiboi]

I just updated to WHM/Cpanel and did a &controlled test& of checkserv, by just bluntly stopping apache. After five minutes WHManager's AIMbot messaged to state that the process for apache had failed and was restarted.

Looks like it's working again, thankfully.

Still having the problem here. Im on build 20, been there since it was released.

I will have Nick take a look at this and see if it is a bug or what. I'm also working out resolving a clients server that is having the same problem . We have over 10 cPanel boxes and not one of them has did this to us

[haze]

the problem seems to have resolved itself with us.
