One more thing: MOM's getStatistics is actually called by VDSM stats reporting code, so my guess here is that someone queries VDSM for stats pretty hard, VDSM then asks MOM for details. Martin On Thu, Aug 31, 2017 at 4:14 PM, Martin Sivak <msivak@redhat.com> wrote:

These are logs from mom's RPC server, someone is calling MOM way too often. Well about 25 times per minute if my math is right.
The only client I know about is actually VDSM.

Be glad to provide logs to help diagnose this. I see nothing unusual in the vdsm.log
mom.log shows the following almost as frequently as the messages log entries

This change was backported to 4.1 and you can find it in 4.19.7+.
This log entry appears in the logs when a client disconnects. 3 seconds is much too often and the only client could do it is mom (adding Martin to confirm).

Hello,
This is not an error and it was modified to reduce logging level. Which vdsm version are you using?
Thanks, Piotr
