https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D225791 --- Comment #25 from Richard Paul <richard@primarysite.net> --- This has been sat on my to do list for a while. I'm hoping that if I can g= et my next job out of the way this week I'll revisit this. Further to my previous posts we seem to see that on instances faced with moderate memory pressure whilst also seeing reasonable amounts of writing to disks that are running on ZFS datasets the reboots seem to happen more regularly.=20=20 We don't see this just where there is memory pressure, e.g. Varnish servers which are running purely within memory we haven't seen this even though the memory usage is very close to 100%. If we double the memory on a crashing instance, the issue goes away.=20 As such I'm going to attempt to force memory pressure on a test server with= an additional disk with a zpool and zfs dataset to attempt to reproduce this = on a recent 12.0 instance. --=20 You are receiving this mail because: You are the assignee for the bug.=
