OK, I've done some more tinkering.
I havn't found a better way to trigger this then to open a Word doc, type
some, save, sit around, type some, save, sit around. It takes patience...
After a while the save fails and Word pops up the following mesage:
The save failed due to out of memory or disk space.
In this example the initial smbd has pid 19957, I have rasied it's debug
level to 10 with smbcontrol, se the attached logfile.
I did the save a Word document dance. Suddenly it freezes for about 30
seconds, then it pops up the mesage.
A quick look with smbstatus:
[root at olivia bin]# ./smbstatus | grep ohrn
ohrn ohrn staff 20033 canine (18.104.22.168) Mon Aug 12 14:43:28 2002
19957 DENY_NONE 0x2019f RDWR NONE /olivia/home3/sys/ohrn/foobar/~WRL0005.tmp Mon Aug 12 14:43:26 2002
Notice that I am now served by pid 20033 and pid 19957 is dead.
Apparently it's pid 20033 that refuses the save, unfortunatley I don't
have any logs since the debug level is reset back to 0. Tomorrow night
I'll change it directly in the smb.conf and redo the experiment.
The next observation is that pid 19957 didn't crash, atleast not in a way
that is caught by 'panic action'. I have double checked my gdb recepie
by manually doing kill -SEGV and that works.
Options if interest are: oplocks = no, deadtime = 0, keepalive = 30
A correction of the topic, it's v2.2.6-pre1, I forgot that it was still
up and running.
This is on a linux box running kernel v2.4.19 in case it's of any
The client is running Windows XP.
So, what do I do next?
