2.0.2 is working stable so far. Thanks for you help and repository suggestion. 🙂

Should netxms crash again, I'll install debug packages and run netxmsd under gdb again.

Can you run NetXMS under gdb?

Also in case of crash provide information about OS, NetXMS version and in case of server information about database.

Thank you!
