Strange app crashes on netbsd-4 MP

[Brad du Plessis <bradd%cat.co.za@localhost>]

Hi all,

For some time now on a number of my newer field systems running a 
GENERIC.MP netbsd-4 (i386) kernel I've seen a few crashes in different 
apps I have running on these systems. Almost all of them appear to be 
disk write/sync related. I've also tried running a single core GENERIC 
kernel and haven't seen any crashes.

Code here was writing text to a file:

#0  0xbb905fef in write () from /usr/lib/libc.so.12
(gdb) bt
#0  0xbb905fef in write () from /usr/lib/libc.so.12
#1  0xbb9a2440 in __swrite () from /usr/lib/libc.so.12
#2  0xbb99f9d0 in __sflush () from /usr/lib/libc.so.12
#3  0xbb99fa65 in fflush () from /usr/lib/libc.so.12
#4  0xbb99f8b3 in __sfvwrite () from /usr/lib/libc.so.12
#5  0xbb977071 in fputs () from /usr/lib/libc.so.1


This was a call to commit a transaction in a Berkeley db library:

#0  0x0818a2b3 in fdatasync ()
(gdb) bt
#0  0x0818a2b3 in fdatasync ()
#1  0x080f8549 in __os_fsync ()
#2  0x080e846a in __log_flush_int ()
#3  0x080e93e3 in __log_put ()
#4  0x080ff5cb in __txn_regop_log ()
#5  0x080fd3cb in __txn_commit ()
#6  0x080fd76e in __txn_commit_pp ()

Has anyone come across this before? Any ideas?


Thanks,
Brad
