McAfee VirusScan Enterprise 8.0i Causes Memory Leak When Scanning Scripts

Metastorm

The information in this article applies to:

Product: Metastorm BPM
Version: 6.x 7.x

Issue

• Metastorm BPM users may get error messages when trying to open folders, take actions, or submit forms that call VBScript or JScript scripts.

• When the Metastorm Process Engine executes scripts, memory usage by the dllhost.exe process used by the Engine account continues to increase without fully releasing (indicating a memory leak). Eventually, the Engine stops responding and must be restarted.

Resolution

• This is a known issue with McAfee VirusScan Enterprise 8.0i. It is caused by the McAfee ScriptScan component, which causes memory leaks in third-party applications that use the Windows Script Host to process VBScript or JScript scripts. This includes the Metastorm Process Engine.

• According to the McAfee website, this problem is resolved in McAfee VirusScan Enterprise 8.5i and in cumulative patch 13 and later for 8.0i.

  NOTE: Additional problems have been reported when using Metastorm BPM with patch 13. It is recommended that patch 15 or later be used.
