Re: ZFS deadlocks/memory accounting issues

i have had problems like this for long time but on 13.* and ram was absolutely tiny

problems seemed to appear when something mmapped files on zfs

problem has puzzled me years and if i limit mmap, nothing fails. except if maybe the strange file errors in some memory pressure cases

unrelated?

some also had questionable similar issues just a while ago on Actual Servers (TM)

same issue, processes get killed

or in this case here, wired doesn't rapidly increase?

also io speeds seem to affect stuff or i don't know what to think of this

but problems described here also involve some mysterious memory usage in zfs. don't know
