daily server down issue

[jai11]

Hello,

I had setup whm/cpanel WHM 11.46.2 (build 4) to host my own websites on linux CENTOS 6.6 x86_64.
Server Version: Apache/2.2.29 (Unix) mod_ssl/2.2.29 OpenSSL/1.0.1e-fips mod_bwlimited/1.4
Server Built: Jan 19 2015 18:37:52
Memory: 15216296k/15728640k available (5336k kernel code, 388k absent, 511956k reserved, 7017k data, 1288k init)

My all sites on this server goes down daily around 8.40pm approx and I am unable to figure out the issue. I am using 16 gb ram and 4 processors Intel(R) Xeon(R) CPU E5-2670 v2 @ 2.50GHz, 2494.050 MHz, 25600 KB.

I need help to fix it.

Look in your logs, for example check out /var/log/messages. Monitor the "top" script from the command line around 8.40 to see what process is causing problems. But if your looking for someone to do this work for you then do a google search for server admin.

Hello,

Yes, Right you will have to monitor your server process through top command. May be you are getting this issues due to high load so following thread may be of help to you:

Hey,
I had this exact problem back in the days: occasionally a job ran and somehow it broke ipaliases for me. so the sites were unreachable until ive logged in and restarted the service.
Its just a hunch but give it a try:
You should monitor things and log in to a console at the estimated time of the issue and see what happens. of course first you should check cron and other schedulers to see what happens at that time. Backups for instance? they do hammer the disk io which might also cause issues like this.

Hello

Try reviewing /usr/local/apache/logs/error_log at the time your websites were not accessible to see if you notice any particular error messages.

Thank you.
