joelones Posted March 17, 2015 Share Posted March 17, 2015 Not too long ago, I've been experiencing monthly or so crashes due to out of memory smbd issues. I wasn't able to get logs at this point, have a screenshot though. Only running the openssh plugin, and have nfs/smb enabled. Currently running ESXi with 6-7 hosts with 16GB total, so memory is somewhat a commodity. The obvious answer would be to start allocating more RAM, although I'd thought 4Gb would be sufficient. unRAID 5.0.6 ESXi 5.1.0 unRAID guest with 4GB of RAM, +30TB disk space of which 50% is uesd.

Are you using memory ballooning on unraid causing memory to be shifted to other vms on your setup? Quote Link to comment
joelones Posted March 17, 2015 Author Share Posted March 17, 2015 I guess the default behaviour is for it to be enabled. Found a KB article discussing how to disable memory ballooning by adding a Configuration Parameter. Hopefully that addresses the crashes. Although found this article saying that it's not good practice to disable the baloon driver... http://blogs.vmware.com/vsphere/2012/02/disable-ballooning.html Wonder if I should just click the checkbox "Reserve all gues memory (All locked)" instead?

mac4685 Posted March 19, 2015 Share Posted March 19, 2015 I was having the same problem before i upgraded my hardware when I had 4GB of RAM. I just enabled a paging file on my cache drive with another 4gb. Problem solved for me. Quote Link to comment
kaiguy Posted March 19, 2015 Share Posted March 19, 2015 If you're passing through your M1015's, ESXi should be forcing you to reserve 100% of the allocated RAM (can't pull RAM out if its being used by a dedicated device, I guess). Double check to ensure that's the case, and if not, definitely reserve it all. For me, unRAID works perfectly fine with 4 GB, even when I had a bunch of plugins running on it. Since you're really not running much on top of it, I'd be worried you have a memory leak somewhere. Are you writing a bunch of things to /tmp, for example? How long after reboot do you begin to see this issue? Quote Link to comment
