Hi,
Hopefully someone can help me with this because its driving me up the
wall. I admin a Samba PDC which authenticates through an LDAP backend.
Both the samba server and pam authenticate through the entries in the
LDAP database.
I recently upgraded to 3.0.4 to combat the M$ hotfix that destroyed
password changing. Since then things have been squiffy. All runs fine
(apart from a grouping problem that I shall describe later) until a
rogue samba thread appears which is owned by "nobody".
PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME CPU COMMAND
2639 root 20 0 13844 3832 804 S 40.8 1.5 4317m 0 slapd
7889 nobody 15 0 1528 492 372 S 4.9 0.1 76:19 0 smbd
This particular top output is probably a bad example because the nightly
backups are running at the same time. However the exhaustion of slapd as
shown above occurs at the same time as this "nobody" thread appears.
When the backup is not running the smbd thread usually hits about 40%
CPU as well leading to a very congested fileserver. At this point the
network slows to a crawl, killing these processes stops the slapd cpu
usage but seems then to corrupt peoples smb sessions which seems to
suggest the process is actually associated with a user.
In trying to track down this bug I've rearranged the entire ldap tree;
we used to have an "ou=smb" tree for all samba classes and "ou=People"
and "ou=Group" trees for all the posix classes. These have ow been
rearranged so that ou=People,ou=Computers and ou=Group exist with both
their posix and samba attributes in each respective tree.
I would really, really appriciate any help that you people can give.
I've had success tracking down samba problems in the past but this one
has me.
