The Symantec Workflow Server service, LogicBase.ServerExtensions, consumes up to 1.5 GB RAM

Products

• IT Management Suite

Issue/Introduction

An ITMS clean install was done. Immediately after ITMS installed, the Workflow server (..\Altiris\Workflow\Server Extensions\LogicBase.ServerExtensions.exe) consumed 150 MB RAM, but overnight it consumed up to 1500MB which was impacting ITMS server performance.

Environment

ITMS 8.6 RTM (GA), 8.6 RU1

Cause

Known issue: This issue occurs only on an SMP Server where Workflow itself isn't installed/configured manually by the user.

The problem was in the not deallocated unmanaged memory which was allocated for IIS apps management. Our Dev team made sure Dispose() was called for  Microsoft.Web.Administration.ServerManager object each time it is used and abandoned. After the fix, the private working memory set of Logicbase.Extensions.exe is 150 Mbs, which is 10 times less.

Resolution

This issue has been addressed in our ITMS release: 8.6 RU2.

A pointfix is available for those customers with ITMS 8.6 GA and 8.6 RU1. The pointfix is ONLY required for cases of Workflow base (but not full server) installed along with ITMS.  There is an updated DLL with the fix: Logicbase.ServerExtensions.Core.dll

"LogicBase.ServerExtensions.Core.dll" is replaced in "C:\Program Files\Altiris\Workflow\Shared\logicbaselib"
