Summary0001912: Samba4 locks when starting Outlook
Description

Samba4 locks after Outlook logged in, with glibc message in log:

glibc detected /usr/sbin/samba: double free or corruption (!prev): 0x0a813f30 ***

This results in locked Outlook trying long minutes to connect. Also samba process is locked and cannot be terminated by initscript - process has to be killed.

This occurs on my Debian Squeeze (i386) with latest (downloaded and installed today) packages from inverse.ca nightly repository.

Rest of my SOGo installation is working correctly (user can log in, IMAP folders and messages are visible, calendars and contacts are working too).

TagsNo tags attached.

After updating packages today, logged error has changed and Outlook terminates just after this error.

This is how it fails with latest version:

Samba version is same, openchange was updated to 1:1.0.r4107.sogo-1~inverse1.0.

I've also found following error preceding (may be relevant):

Can you try to run samba in single process mode from gdb?

When it "locks up", just hit Control-C and send a backtrace (using "bt" in gdb). You can start samba like this:

gdb --args /usr/local/samba/sbin/samba -d1 -i -M single

Adjust samba's binary path accordingly.

By chance, are you using Samba as its own LDAP server in the SOGo configuration?

I am sorry, but I am not able to test it anymore. I've lost my test system during system update few months ago, because new samba4 package failed to install on my system. This bug persists so I have no working testing environment at the moment.

But for sure I was using Samba as its own LDAP server.

Unfortunately, the tester can't help us anymore with this issue and we can't reproduce it. Closing for now but if someone can reproduce it in a constant manner, reopen the ticket and produce a stack trace.
