https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194513 --- Comment #2 from James Van Artsdalen <james-freebug@jrv.org> --- I was able to complete a ZFS replication by manually intervening each time "zfs recv" blocked on "kmem arena": running the attached program "eatmem" was sufficient to unblock zfs each of the 17 times zfs stalled. Eatmem is intended to consume about 24GB RAM out of 32GB physical RAM, thereby pressuring the ARC and kernel cache to shrink: when the program exits it would leave plenty of free RAM for zfs or whatever else. What actually happened is that every time, zfs unblocked as eatmem was growing: it was never necessary to wait for eatmem to exit and free memory before zfs unblocked. -- You are receiving this mail because: You are the assignee for the bug.
