Message flow suffers severe latency or ceases due to GWGlobalPollThread::ThreadProc -- Unexpected event signaled (-1) being recorded in the log files

Article ID: KB36118

Type: Support Content

Last Modified: 07-14-2014

 

Product(s) Affected:

  • BlackBerry Enterprise Server for Novell GroupWise
CollapseEnvironment
  • BlackBerry Enterprise Server for Novell GroupWise
  • JI 724081
CollapseOverview
The following log line starts being recorded repeatedly in the MAGT logs:

[40000] (06/10 17:31:38.045):{0xED4} GWGlobalPollThread::ThreadProc -- Unexpected event signaled (-1).


This log line is recorded multiple times per second and eventually becomes the sole log entry until a Message Agent restart occurs. The repeated logging of this log line can potentially cause excessively large MAGT logs, each file may reach the default limit of 512MB before a new log file is created, these files will eventually be created every few minutes that risks consuming all available disk space until a Message Agent restart. While it appears the Message Agent will continue processing messages when this incident is occurring, all the logging eventually consists solely by the GWGlobalPollThread::ThreadProc entries and message flow ceases.

CollapseCause
This is a previously reported issue that is being investigated by our development team. No resolution time frame is currently available.
CollapseWorkaround

Restart the BlackBerry Controller Service to reinitialize the BlackBerry Message Agent.

CollapseAdditional Information

This incident has only been seen when there has been an connection interruption to the Microsoft SQL server hosting the configuration database. Under certain conditions the polling thread does not recover and the Message Agent will exhibit the symptoms referenced above.
