We're using MOSS for a public website baased in a two-server farm (DB and MOSS) and we are continually seeing errors raised relating to the Unified Logging Service. Each time these errors occur, the App Pool re-cycles and we loose the site for a short period of time. The errors are occuring fairly regularly, roughly once or twice an hour. Exceptions are as follows:

EventType ulsexception12, P1 w3wp.exe, P2 6.0.3790.1830, P3 42435be1, P4 mscorlib, P5, P6 4333ab80, P7 19501, P8 6, P9 cryptographicexception, P10 8yr8.

Looking in the trace for this one we get many "System.Security.Cryptography.CryptographicException: Keyset does not exist" messages.

Another exception we seem to be getting, although less often, is:

A runtime exception was detected. Details follow.

Message: Exception of type 'System.OutOfMemoryException' was thrown.

Techinal Details:

System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

Is anybody seeing anything similar I've googled this and come up completely blank.
