huge thanks for all the work on this btw!

I think I've found a likely culprit (a missing lock around a 
non-thread-safe corosync library call) based on the last logs (which 
were now finally complete!).

rebuilt packages with a proof-of-concept-fix:

I removed some logging statements which are no longer needed, so output 
is a bit less verbose again. if you are not able to trigger the issue 
with this package, feel free to remove the -debug and let it run for a 
little longer without the massive logs.

if feedback from your end is positive, I'll whip up a proper patch 
tomorrow or on Thursday.
