Re: [ovirt-users] vdsm using 100% CPU, rapidly filling logs with _handle_event messages

I'm running oVirt 3.5.x with a hosted engine. This morning I noticed that 2 of my 5 hosts were showing 99-100% cpu usage. Logging in to them, vdsmd seemed to be the culprit, and it was filling the log file with these messages:

VM Channels Listener::DEBUG::2015-11-12 08:09:26,292::vmchannels::59::vds::(_handle_event) Received 00000011. On fd removed by epoll. VM Channels Listener::INFO::2015-11-12 08:09:26,293::vmchannels::54::vds::(_handle_event) Received 00000011 on fileno 119 VM Channels Listener::DEBUG::2015-11-12 08:09:26,293::vmchannels::59::vds::(_handle_event) Received 00000011. On fd removed by epoll. VM Channels Listener::INFO::2015-11-12 08:09:26,293::vmchannels::54::vds::(_handle_event) Received 00000011 on fileno 75 VM Channels Listener::DEBUG::2015-11-12 08:09:26,293::vmchannels::59::vds::(_handle_event) Received 00000011. On fd removed by epoll. VM Channels Listener::INFO::2015-11-12 08:09:26,294::vmchannels::54::vds::(_handle_event) Received 00000011 on fileno 119 VM Channels Listener::DEBUG::2015-11-12 08:09:26,294::vmchannels::59::vds::(_handle_event) Received 00000011. On fd removed by epoll. I googled to see how to change the debug level to turn of DEBUG messages for vdsm, which referred me to libvirtd.conf, but the debug level there was not set, which should have meant a log level of 3 (warnings and errors), so I'm not sure why the log was filling up with DEBUG/INFO messages. I restarted vdsmd, which resulted in those nodes being marked as 'disconnected', but they did eventually recover and loads went back to normal. This may or may not be related to the fact that the 3 hosts where this did not happen can't seem to keep their ha brokers up. I'll be starting a new thread on that shortly.
