AW: [Users] OpenSER crashed with Segmentation Fault using PresenceModule - sr-users

17 May 2007


      Hello,
here is the stderr console output (just the last lines which should be important as I saw there is a message size limit), and the gdb backtrace.
Do you see any hint for the crash?
Best regards
Sebastian

Dear all
I am currently writing my final thesis and want to set up a Presence Core therefore. I am using OpenSER as Presence Agent (with Registrar function or now with separat Registrar, both configuration has the problem). It crashes after a certain time and certain amount of watcher entries. I cannot replicate this or deliminate to a certain action but it always happends, no matter if I clean up the tables, restart the machine or whatever.
My configuration is one XCAP Server (XCAP Lite 1.0 from ag-projects, working properly), one Registrar (OpenSER with MySQL DB, which forwards SUBSCRIBE/PUBLISH to PA) and Presence Agent (OpenSER with Presence Module, MySQL DB, XMLRPC Module) and Eyebeam 1.5 Clients. All runs on VMware virtual machines.
I have just three clients that try to subscribe each other. Without any Subscriptions everything works properly, XML data gets stored, PUBLISH is processed etc. Subscribing one user by another is possible and works properly.
After allowing a watcher to subscription (using XCAP) and if the watcher logs in next time, the state in the watcher table changes from pending to active. It happens now and then, when a user goes online and one of his subscribed presentities is not online, that the OpenSER PA crashes.
Analyzing DEBUG info and backtrace was not successful, because I found no information or hints about it, just the message segmentation fault appears.
Does anyone have this problem as well or has anybody an idea about it? I can provide you logs, the dump or traces if you need it.
Thanks for your help.
Sebastian
