Description Lon Hohberger 2009-06-22 14:22:43 EDT 
Description of problem:

During event processing, an error in the S/Lang code can produce unwanted S/Lang stack leaks.  This can be fixed a number of ways, for example, purging the stack at the end of each run.  However, the correct fix is to not leak the variables in the first place.

After several hundred events are handled, the S/Lang stack can fill up, requiring a retry of the service operation.  On failover, this could result in a service not running if central_processing is enabled.

Normally, however, it's during a user operation, requiring a retry of that operation.
