I experienced a couple panics yesterday while working with some video files
The panics didn't happen until after an hour or two of sustained activity
(heavy reading and writing to/from multiple files about 2GB in size). The
panic message (most recent) probably looks familiar:
panic:kmem_malloc(65536): kmem_map too small: 757669888 total allocated
This is on an i386 8-CURRENT box w/ the recent ZFS mega-patch applied:
FreeBSD stealth.jnielsen.net 8.0-CURRENT FreeBSD 8.0-CURRENT #0: Mon Jul 28
09:17:49 EDT 2008
john at stealth.jnielsen.net:/usr/obj/usr/src8/src/sys/STEALTH i386
This system is currently running ZFS filesystem version 3.
All filesystems are formatted with the current version.
This system is currently running ZFS pool version 11.
All pools are formatted using this version.
The box has 1.25 GB RAM. The kernel is compiled with KVA_PAGES=384 and
vm.kmem_size and kmem_size_max are set to 768M.
Since the last panic I have set vfs.zfs.arc_max to 160M and I haven't gotten
another one, but I haven't had the same sustained activity since then
either. I'll keep an eye on it.
Just thought I'd send a report since I'm not sure if this is still expected
behavior with the new patch. I am of course also open to tuning
suggestions, though I have read the wiki and kept up on the mailing lists
and am willing to experiment to see what ends up working best for this
