HP-UX 11.00
Samba 3.0.21a PDC
OpenLDAP backend
When we log on to an XP box, the smbd process freezes for one to two
minutes, while taking up almost 100% CPU. However, this does NOT
happen when logging on to an NT box.
We use no roaming profiles, so it's not that XP is copying files or
something. In fact the pc seems to do nothing but wait.
Moreover we often have the same effect when using the pdbedit command
to modify a user's parameter. So the problem seems to be completely
isolated within the samba server (which also runs the openldap).
Below some extracts of log.smbd; two during an XP logon and one during
a "pdbedit" command. And also our smb.conf.
I inserted "..... PROCESS FREEZES HERE ....." where the process (smbd
or pdbedit) froze while consuming all the server's CPU. As you see
there seems to be no real error at that time, the process just stalls.
This all happens on test server, with just a few pcs connected (so the
servers aren't busy at all).
Any ideas?
