Alarm Console - runtime errors (RTEs)

About runtime errors

RTEs occur when a DataMiner process thread does not respond for 15 minutes. Half-open RTEs occur after 7.5 minutes.

These are notable exceptions to the 15-minute window:

  • SLDataMiner DataMinerNotificationQueueThread: 45 minutes

  • MySQL DatabaseOffloadThread: 30 minutes

  • MySQL DBCleaningThread: 1 hour

When an RTE occurs, an alarm is generated in the Alarm Console, the RTE is logged in SLWatchDog2.txt, and all DataMiner log files are captured in a minidump.

Identifying runtime errors

  • RTEs are displayed with severity "Error" in the Alarm Console.

  • RTEs have the value "Thread problem in x: y” in the Alarm Console, where x is the process, and y is the thread.

  • You can identify RTEs by opening SLWatchDog2.txt (in C:\Skyline DataMiner\Logging or in minidumps) and searching for “RTE Count = 1” (spaces included).

  • Minidumps are named based on the RTE timestamp and DataMiner process that encountered an RTE.
