Is there any possibility of someone helping me look at this? I'm
seeing
the issue much worse with 4.3 - a cluster I updated to 4.3.7 two
months
ago has a host (where the hosted engine was running) where vdsmd
got to
over 20G RSS.
Marcin, any suggestions how to investigate it?
Python mem profiling is hard... I already tackled the VDSM memory leak
problem once.
VDSM was growing, but not at a scale that Chris is describing. Tried out
different tools,
but got to a point, where enforcing periodic garbage collecting made
VDSM mem usage
constant, so the conclusion made there was no mem leaks.
Chris, if I understood you correctly, a single machine suffices to
reproduce your issue?
One that acts as a host with hosted engine on it + iscsi storage?
If so, maybe I/you could construct a VM with a reproducible environment
and share?
Having something like this would make investigating this issue much more
reliable.
