OK, 32-bit x86. The 32-bit x86 kernel is limited to 512 mbytes of kernel heap
space, maybe that box is running out of free kernel heap memory?
zfs is using lots of kernel heap memory.
Do you have a saved panic crash dump from that server, in /var/crash/`hostname`
?
What is reported by
$ mdb -k 0 (replace 0 with the suffix from the unix.N vmcore.N files
that have been saved)
::memstat
::kmastat
