We are seeing alerts from various message channels that just say 'S_BUFFER.xxxx' where x is a number.
That's all I can tell you, there is no other content. The original message is actually blank.
Obviously these are passthru's. The POWERpack_Log only shows an entry for each occurance as being sent to the alertserver, nothing about where they have come from.
Where are these coming from, why and how?
