statistics_collector takes 12-15 hrs to complete

[gennolo]

I am running Plesk 12.5.30 on several Centos 6.7 VMs.
From some days some VMs takes hours to complete the nightly "statistics_collector" thing (up to 12/15 hours) and increases load average of the VMs themselves.

Usually the process had always took 3-4 hours to complete and I am puzzled in troubleshooting this.

"ps auxf" on the involved boxes show this situation for the most part of the process:

So it appears statistics_collector staying in "uninterruptible sleep" status.

BTW - What is this process doing ?

awk -v progname=/etc/cron.daily/50plesk-daily progname {?????   print progname ":\n"?????   progname="";????       }????       { print; }

I had problems with statistics_collector in the past resulting my VMs to have high I/O (I upgraded disks to more performant hybrid-NFS storage and the problem seemed partially resolved until today).

Any idea to better troubleshoot what's happening or what part on statistics take so long to complete?
Note that I have already disabled web-statistics on all domains.

Thanks for the help.

Hi Igor,
My mistake - I had the previous topic bookmarked to the "old" Odin forum (http://forum.odin.com/) and I didn't realized it was migrated here too so I started a new discussion.
Feel free to close / delete old thread or to move this update in the old discussion.
