Hi,
two of our smp linux web servers (2.2.12smp) were running fine for about a year until a month back. now they crash randomly from a week to a couple of days giving wait_on_bh oops. that can happen during both busy and not so busy times. following is the message we receive,
wait_on_bh, CPU 0:
irq: 0 [0 0]
bh: 1 [0 1]
<[c010a385] [c016881e] [c0162e6b] [c0163108] [c016f91e] [c01533cb]
[c01537c5] [c012611d]

and the mapping
c010a385: synchronize_bh
c016881e: tcp_v4_unhash
c0162e6b: tcp_close_state
c0163108: tcp_close
c016f91e: inet_release
c01533cb: sock_release
c01537c5: sock_close
c012611d: __fput

appreciate any help,

regards,
saans

You may actually want upgrade that kernel, as most likely this error has already been addressed by later kernel releases.
