Hi,

My kernel has been crashing like crazy at unexpected times, usually
during heavy load (usually while I"m compiling something).

I had no idea why, but on recommendation of someone on the list I
installed a debugging kernel and set dumpdev in my /etc/rc.conf file.

Here is the tail of my /var/crash/vmcore.0 file:

-------------------
mode = 0100644, inum = 450752, fs = /usr
panic: ffs_valloc: dup alloc

syncing disks... 119 117 91 61 28 7
done
Uptime: 1d18h32m12s

dumping to dev #ad/0x20001, offset 163840
dump ata0: resetting devices .. done
48 47 46 45 44 43 42 41 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24
23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2

------------------

Does this help at all in diagnosing the cause of my crashes?


Regards,
Trevin Chow
