Problem with winbind

Comments

I have several linux servers integrated to an Active Directory using winbind. The problem is, sometimes when logrotate sends the sighup signal to smbd, nmbd and winbindd, winbind crashes. I've only found a bug report on this issue, closed because the error can't be reproduced.

This is what I get in the winbind.log . Somebody has got the same problem?
