Hi,
I'm experiencing vpxa crashing due out of memory with 5.5 (esxi build 3116895, vcenter 3142196). Hosts goes offline in vcenter and after a while it reconnects. Probably from update to this version in autumn.
vpxa process:2015-11-20T08:00:31Z Unknown: out of memory [34516]..2015-11-20T08:00:31.935Z cpu0:54442)UserDump: 1820: Dumping cartel 34516 (from world 54442) to file /var/core/vpxa-worker-zdump.000
I had opened it twice with vmware support and they advised to increase ThreadStackSizeKb in vpxa.cfg. It was ok for few days (or just maybe restart of vpxa) (and period of crashed seems to be longer?) Anyway, I have opened it once more and answer from support was that it is due lot of snapshots - we had few vms with more than 32 (officialy supported number). We had deleted more than 32 snapshots and...still crashing
We are not with latest 5.5, but I'm unsure if upgrade will help. Due sslv3 patches I have to upgrade vcenter first, I can't patch hosts to try -- anyway vpxa is installed and upgraded from/with vcenter right?
