I am occasionally getting errors that are freezing up the CAS, preventing mail transmission until I restart services. Most of the errors I get are similar to the one below, they ALL have to do with RPC. Using Exchange 2010 SP3 (where did all the 2010 forums go? couldn't find, so am posting to the 2013 forums, sorry). I turned on windows error reporting settings in the registry to dump the error log, but absolutely nothing shows up so that is no help. The information I find mostly points to installing rollups (most of the rollups are older than what I have installed). I don't have any really definitive information here and it is getting frustrating. At least this time I got the exact same error at the exact same time on both of my CAS servers instead of getting it on one CAS server, and this time it showed up BEFORE all the systems froze, instead of after everything came back, so at least I could start checking/restarting services, etc. Any ideas here? Thank you.
