What causes my entire server to go down?


Up to the last month or so, my server with Servermatrix has been rock solid, with no downtime. For some reason, though, I've had every service on the server fail three times in the last month, and the only way to bring everything back online is to reboot the server.

There doesn't seem to be any other warning signs before this happens - CPU usage doesn't spike, and hard drive space usage is just fine.

Can anyone give me some pointers on where I should be looking to try and figure out what's causing this server-wide crash? It's running Red Hat Enterprise with Cpanel and WHM.

Thanks!

Neil

I had a similar problem with my server once working all fine then in a span period of a couple of weeks it used to go down for no reason at all nearly or if not everyday

every trick in the book was tried but still it kept going doiwn and like urs we needed a reboot to get it back up...it wud come back up then die 24 hrs later or on so...

possible causes we found out where hardware..the power supply was the main cause

u may wanna get ur DC to check the power supply or maybe a memtest even..

this was done in our case

Is memory usage a concern?

I was wondering if it could be a hardware issue. Memory, I believe, is okay.

I was a big idiot, though, and accidentally had my IPAlert monitoring email as an email on the server. So all of the server warnings about the problem weren't being sent.

Whoops.

You can usually see memory usage problems coming. If it happens repeatedly and without warning, power supply and cooling are good first candidates.

you can check your logs to see if theres any signs of anything
also if you think its the memory, run memory tests and see what happens....

1. Memory test to be done immeditely.
2. Hard disk to be checked .
3. Kernal Hanging will give the above troubles. Update your software to recent stable versions.
4. There is some faulty switch . It takes full power with in few seconds and sucks the server power supply.
5. You utilised more then 80% of your space.

These are the possible reasons.

We found that servers which go down for no explainable reason, can be attributed to defective hardware most of the time. It's either bad memory or power supply related in many cases. Sometimes just loose cables and/or DIMMS, or improper cooling will cause these problems.

With issues such as this, we usually try removing the hard drive(s) from the server and putting it into a new box. About 80% of the time this fixes it.

WARNING: Kernel Errors Present
hda: drive_cmd: error=0x04 { DriveStat...: 1Time(s)
hda: drive_cmd: status=0x51 { DriveReady SeekComplete Error }...: 1Time(s)


as my server keeps crashing for some reason do u think that above has something to do with it?

Unless you see recovery messages (which you clearly don't), it means your hard drive is about to puke.
