[jdev] Session Manager crashed

[Lucas Alvarez]

Hi, I'm running jabberd version 2.0s10 in RedHat EL4. This morning there 
were 900 users logged on and the Session Manager crashed. I'm attaching 
below the full backtrace of the core file, perhaps we could be in the 
presence of a bug and some more skillfull dev could find something out. 
Thanks in advance.

Lucas Alvarez
