Hello, Robert and everyone.
Time to time our Application servers do crash (the
service stops), producing events similar to this one in the
witangoevents.log:
[ 4228] 2012-03-08 14:37:45 RUNTIME ERROR Unexpected exception has
been caught trying to delete a meta object.
[ 4228] 2012-03-08 14:37:45 RUNTIME FATAL An unrecoverable OS
exception has been caught in the Main Application Thread

We run different applications on different machines, each one has
registered such issues at least once before. Sometimes we could go by
without a single crash for months. And sometimes the server crashes
twice or three times per day.
So, It looks like a certain operator within the TAF file has caused this
App Server crash.
Would there be any recommendations as to how to debug such events,
perhaps there’s a way to read a crash dump?
