  • On a Domain Manager running ENC Server, the windows system process lsass.exe consumes memory and it never releases it. This causes the server to become unusable after about 24 hours as it may have taken almost all the physical available memory of the computer.
  • Stopping the ENC server processes allows lsass.exe to release the memory in about 15-30 minutes.


  • Client Automation 12.8 FP1.


  • The reason for this issue is the large amount of handles which get created when the process calls the function AcquireCredentialsHandle.
    The Java.exe process was not properly calling FreeCredentialsHandle to free those handles, causing the memory leak.


  • Open an issue with CA Support and reference: DTSVMG problem# 3472.
  • T5J1377 resolves this problem.
