Groove Server Relay errors and events

 

Applies to: Groove Server 2010

Topic Last Modified: 2011-09-10

This article provides reference information about Groove Server Relay event log codes and messages. Groove Server Relay assigns a unique number to each event message that appears in the Windows Event Log. Microsoft Operations Manager (MOM) and other tools that scan the Windows Event Log to automate server monitoring tasks (such as the Windows tool eventtriggers.exe) can reference these numbers.

Different categories of Relay server events fall into specific numeric ranges, as summarized in the following table:

Event Message Code Range Event Category

0 - 99

Reserved

100 - 2999

General Relay server

3000 - 3999

Database

4000 - 4999

Resource Monitor: MemoryLoadGreenFlowControl Set MemLoad[75] (LWM[70] HWM[75]) Current Enqueue Bytes : Local[0] Transit[11563767]

Resource Monitor: MemoryLoadYellowFlowControl Set MemLoad[85] (LWM[80] HWM[85]) Current Enqueue Bytes : Local[0] Transit[10141491]

Resource Monitor: MemoryLoadRedFlowControl Set MemLoad[92] (LWM[88] HWM[92]) Current Enqueue Bytes : Local[0] Transit[10076734]

Relay Server memory load has reached a threshold that requires a level of flow control, based on per-session bandwidth usage. The system applies flow control automatically and dynamically, based upon instantaneously measured memory load. Incoming client-originated messages contribute to memory-load until they are successfully written to the local disk, or transmission to a remote Relay server has been acknowledged.

Flow control events are generated for Relay servers that have over 8 gigabytes of memory, as part of the Groove Server 2010 Relay memory-based flow control service. Event messages indicate that a memory usage limit has been reached which starts a level or zone of flow control (indicated by color), as follows:

  • Green - Memory load has reached 75% and a flow control zone has been set for a memory usage range of 70% to 75%. %. Flow control is applied only to sessions with large memory requirements. This level of flow control persists until memory load drops below the range or until memory usage reaches the level for the next zone.

  • Yellow - Memory load has reached 85% and a flow control zone has been set for a memory usage range of 80% to 85%. Aggressive flow control is applied to sessions with large memory requirements, while less aggressive flow control is applied to sessions that present a smaller load. This flow control level persists until memory load drops below the range or until memoryusage reaches the level for the next zone.

  • Red – Memory load has reached 92%. To ensure that the system does not fail, dynamic flow control is applied to all incoming traffic (by writing the queued messages to disk or by completing transmission to remote Relay servers) until memory consumption falls below 88%.

Note

To avoid memory overload conditions and associated server shut-downs the Relay server sets a maximum number of allowable connections, based on the amount of installed memory. For example, for Groove Server 2010 Relay installations with 16 GB RAM or more, the system imposes the following hard Relay server connection limits:

  • SSTP (ports 2492 and 443) - 52,500
