Mark,
Could you please file a bug report?
Restart of vdsmd service would help to resolve the “executor queue full” state.

Hi,
To try and get a baseline here I've reverted most of the changes we've made and
am running the host with just the following iSCSI related configuration
settings. The tweaks had been made over time to try and alleviate several
storage related problems, but it's possible that fixes in Ovirt
Hi Nir,
Thanks very much for your feedback. It's really useful information. I keep my
fingers crossed it leads to a solution for us.
All the settings we currently have were to try and optimise the Equallogic for
Linux and Ovirt.
The multipath config settings came from this Dell Forum thread
Just been catching up with all the threads and I saw mention of some
iscsid.conf settings which reminded me we also changed some of those from
default as per the Dell Optimizing SAN Environment for Linux Guide previously
mentioned.
Changed from default in /etc/iscsi/iscsid.conf
