(zmstat) high CPU load after reboot

Post by pgrzeda »

Hello,

Zimbra version zcs-8.8.10_GA_3039.RHEL7_64.20180928094617.tar
CentOS Linux release 7.6.1810 (Core)

After each reboot of my VM with Zimbra something bad happens with the zmstat module. After zimbra service starts correctly a huge input is being made to file /opt/zimbra/zmstat/io-x.csv When I ls -la /opt/zimbra/zmstat/io-x.csv I can see growth like 50 MB per second. It grows to 40 - 50 GB even. After that the file is being gziped into /opt/zimbra/zmstat/io-x.csv.gzip
Whole process takes a lot of RAM and CPU, and makes it almost impossible to use this VM, After process finishes VM becomes nice and stable.
I found similar problems on the forum but with no resolution.

Any help? Is there a way to disable from stats only io-x ?

This is absolutely new installtion with no single e-mail sent or received yet. I was preparing this instance to go productional, testing backups, provisioning etc. After one of reboots it just started to happen.
