Dreaded ORA-07445 error

Late yesterday one of our projects passed me information abvout an ORA-07445 error they'd had earlier in the day, apparently this is stopping one of the modules in their application to stop working. Why they couldn't have told me about it earlier I don't know, I would have had time to raise a Service Request with Oracle during our maintenence hours (the why we don't have 24x7 cover is a rant for another time).

I raised a call with Oracle before I went home but there's been no updates on it as of yet, other than a note saying they will update it when they have some information (fair enough I suppose). This long silence is worrying, maybe it's something serious?

Here's the header of the trace file:

See Metalink note 4098853.8
Bug 4098853 - Dump (qerixGetKey->evaopn2) using COUNT(NOT_NULL_COLUMN) with a view.

There is a workaround documented

Cheers!
