Bug ID: 231794 Summary: Panic in ZFS due to arc related memory exhaustion Product: Base System Version: 11.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: b...@freebsd.org Reporter: davewrobi...@gmail.com Created attachment 197582 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=197582&action=edit Photo of backtrace We are evaluating two servers based on the HP DL360 G10 (16 gigs RAM) and HP DL380 G10 (32 gigs RAM) motherboards. We can routinely panic these machines by putting them under load while running ZFS. Running six instances of bonnie++ and six instances of memtester (testing 2g) is enough to panic the DL360 in around 15 minutes and the DL380 in 10-13 hours. Reducing ARC dramatically using vfs.zfs.arc_min and vfs.zfs.arc_max seems to mitigate this problem, at least after a day of testing under 12.0-A7. We are testing now on 11.2-RELEASE which we will use in production. Daiichi from Japan was here to help diagnose this problem, and has been in contact with core team members who requested this bugzilla submission. More panic photos available on request. -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ freebsd-bugs@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
