[ovirt-devel] vdsmd memory leak
I've seen vdsmd leak memory (RSS increasing) for a while (brought it up
on the lists and opened a BZ ticket), and never gotten anywhere with
diagnosing or resolving it. I reinstalled my dev setup Friday with
up-to-date CentOS 7 (minimal install) and oVirt 4.3, with a hosted
engine on iSCSI (multipath if it matters).
In just 3 days, vdsmd on the host with the engine has gone up to an RSS
of 481 MB. It just continues to steadily increase. Watching with a
script, I see (this is VmRSS from /proc/$(pidof -x vdsmd)/status):

That's an increase of 352 kB in a minute.
There's got to be some way to diagnose this, but I don't know python
well enough.
