Backups not completing properly

[webmasteryoda]

Hello

My backup was working just fine.

10 days ago I discovered that my VPS is running on very high CPU usage all the time.
I figured out that my automatic backup is NOT finishing as fast as before.

I have more than 80 accounts, and it takes time until it finishes (usually it takes 1 day - I do it on sundays).

But previous backup and the one before (last 14 days) takes too looooong to finish...

Those are the error messages:

I upgraded to Easy Apache 4 and PHP 5.6, but I dont think that these changes caused this problem.

Any clues?

Hello,

I think you have set load threshold in WHM and that's why process stop when server load goes high. Please check setting using below steps.

Login to WHM >> Server Configuration >> Tweak Settings >> Critical load threshold

It should be default.

 

[webmasteryoda]

Yes, I have found it.

It was set to 6, but I didnt change it.
So, now I have switched to "default" and I hope its gonna work...

I ll let you know.

Thanks

 

[webmasteryoda]

Well. The problem stays.

The other options is "Default", but there is also written "# of CPUs (autodetect) default".

As I have 6 CPUs, cPanel automatically sets my threshold to 5.25.
But, if I put it manually to more than 5 (6, 7, 8...) system is not responsive as usual.

Hello,

The actual option that affects whether backups run is "Extra CPUs for server load", located under the "Stats and Logs" tab in "WHM >> Tweak Settings". Per it's description:

The load average above the number of CPUs at which cpuwatch, cpanellogd, backups, and CPU stats consider the system to be in a critical load state. For example, a server with 4 physical CPUs and a value of 2 in this field will be considered “critical” in these cases once the load reaches 6.

Thank you.

Ah, I understand now.

But it seams that something else caused high CPU usage while processing the backups. It finally finished.
I ll try to detect the real cause of the problems.

Hello,

You may find the following thread helpful when troubleshooting the high load average:
