Comment 2 Alon Bar-Lev 2013-07-22 10:44:39 UTC
This is interesting!

The following should not be in log:

2013-07-19 13:51:43,245 WARN  [org.ovirt.engine.core.compat.backendcompat.PropertyInfo] (VdsDeploy) Unable to get value of property: vds for class org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogableBase

However, I do not think it is related.

I found no reason why at random times we get interrupted exceptions at engine side.

Can you please try to stop engine then start and re-try? I would like to see a fresh start of this, if this repeated I will need engine log in debug level, something is happening that I cannot see.

Comment 7 Alon Bar-Lev 2013-07-22 14:23:55 UTC
Hello Yair,

Any reason why we see the following? can it cause any issue? does it imply data model issue?

I cannot see anything that goes wrong... until this interrupt.

Firewall rule was killing SSH sessions with 10+ seconds of inactivity.
