Informix 7.10.UD1 Online Engine Crashed Big Time

Fellow 7.1 Administrators: This afternoon, we had a development instance of Informix 7.10 come crashing down around our heads. At around 2:30, we had an assert fail and Online aborted. Several developers got the message that both the primary chunk and it's mirror were corrupt. Since it was chunk 2 and the only chunk whe have mirrored is rootdbs, I assume it was rootdbs. Below is a copy of the log. I wonder if any of you have experienced similar problems? Or does anyone know if this is due to a bug which is fixed in a more recent version? Thanks for your help.
