[ovirt-users] vdsm vds.dispatcher ERROR SSL

Fri Oct 21 12:45:43 UTC 2016

Baptiste,

It would be great if you could provide engine log with debug log level enabled.

In ovirt-engine.xml.in file please update following entries:

      <!-- Loggers for the engine: -->
      <logger category="org.ovirt" use-parent-handlers="false">
        <level name="DEBUG"/>

      <root-logger>
        <level name="DEBUG"/>
        <handlers>
          <handler name="ovirt-logger"/>

Please provide vdsm log from the same time as well.

Thanks,
Piotr

It seems that the "vdsm vds.dispatcher ERROR SSL error" occurs only on the SPM node as we noticed that these logs disappears when another host is selected as SPM, and we can find these errors on the new SPM host. We have multiple DCs, one with the hosted engine, and others with only simple hosts. The problem don't occurs on the hosted engine cluster in our deployment. This problem seems related to instability on this cluster, the SPM host fall in unresponsive state mostly every 4 minutes and comeback during the grace period most of the time (but was fenced 1 or 2 times last 2 weeks).
