Error messages in event log - bucket table 5

I keep getting this error in my event log:

Bucket 04944163, bucket table 5, EventType sql90exception, P1 w3wp.exe, P2 6.0.3790.1830, P3 42435be1, P4 sqldumper_unknown_module.dll, P5 0.0.0.0, P6 00000000, P7 0, P8 0f1e826d, P9 00000000, P10 NIL.

SQL server 2005, Windows 2003

I cannot find anything on the web or in help about this - any clues anyone?

What kind of app are you running- a Windows Service, Web Service, etc?|||

|||I am using SQL 2005 RTM within an ASP page. Our whole reporting server crashed witha refusal to display any reports this morning. No clues as to what was wrong, then it came up - no rhyme nor erason to it. Anyone have any ideas?
