samba-TNG Re: Problems with oplocks

[Luke Kenneth Casson Leighton]

hi tom,

there is a way to catch this with gdb if there is no corefile: you put a
sleep(20) or maybe even a sleep(60)) which gives you more than enough time
to notice the problem if you are running grep INTERNAL log.*, and fire up
gdb bin/.libs/smbd in advance, and then jump on that and do attach 739 (in
this case, because 739 is the process id).
