My server is rebooting frequently throughout the day. No apparent rhyme =
or reason, different applications can cause it. The following is what I =
get from one of the backtraces.


(kgdb) backtrace
#0  0xc055c5e2 in doadump ()
#1  0xc055cb82 in boot ()
#2  0xc055ce18 in panic ()

#20 0xc057abbb in turnstile_wait ()
#21 0xc0554565 in _mtx_lock_sleep ()
#22 0xc05543dc in _mtx_lock_flags ()

It seems that pretty much every time I've traced the dump, it's always =
the turnstile_setowner that causes the panic. Or am I reading this =
wrong?

Any thoughts or further debugging tips would be appreciated.=20

TIA,
Steve
