Here is what it said. panic: kmem_malloc(131072): kmem_map too small: 167264256 total allocated cpuid = 0 KDB: enter: panic [thread pid 37 tid 100042 ] Stopped at kdb_enter+0x32: leave db> :( At the time this happened I was transferring lots of files to this system (personal file server) via the Apple File Protocol -- netatalk. It went fine for a few GB. Then this happened. The reason I'm running current rather than stable is that ZFS is a selling point.(but opensolaris doesn't work for me...) I have a zpool with 2 hard drives and 1 partition of a slice of another disk that is shared with root and swap. Mirroring isn't on. This farily old PC has a Pentium III Tualitin Celeron, and just 512MB of RAM. But the unrecommended minimum is 1 GB for ZFS. So I'm not sure if the problem is... I'm out of RAM. But I watched the memory usage and it didn't go up. Swap wasn't touched at all. Network related? Googling for the error I got got something I believe is unrelated. Or something else. Anyway I'm leaving the machine on in case anyone could use a trace if it helps. Thanks in advance!
