Segfault with huge backtrace (UnloadGrid and/or DestroyInstance ???)

[fdb_]

Here is a pretty huge back trace of a segfault: http://paste.ubuntu.com/389280/

The server has been compiled without any optimization and with maximum debugging options.

Seems UnloadGrid and Instance involved in it.

I am not able to reproduce it, and it happens randomly on few to high populated server.

Any kind of feedback will be very appreciated.
