While testing some new hardware on a recent RELENG_14 image (from Nov
10th), I noticed some of my ssh sessions would get killed off with the
errors below (twice in 24hrs)
pid 1697 (sshd), jid 0, uid 1001, was killed: failed to reclaim memory
pid 6274 (sshd), jid 0, uid 1001, was killed: failed to reclaim memory
Nothing fancy bencthmark wise, I am just testing a whole mess of HDDs
off a backplane by generating some synthetic traffic on a big pool of
disks. 65G of RAM. ARC is not limited and seems to try and take the max
possible. Any ideas what might be going on ?
