SLNet handle leak caused by SAML authentication and SLHelper startup

Affected versions

DataMiner 10.5.0 [CU12], 10.6.0, and 10.6.3 [CU0].

Cause

Logger instances used in SAML authentication and SLHelper-related flows are not correctly disposed. As a result, handles are not released after use.

Fix

Install the latest, patched version of DataMiner 10.6.3 [CU1], 10.5.0 [CU12], or 10.6.0.

Workaround

If the handle leak is caused by BPAs running on the system, adjust the BPA schedule to run them less frequently as a temporary workaround. See Running BPA tests.

Description

The SLNet process gradually leaks handles when:

• A user authenticates using SAML.

• An SLHelper process is started.

  Notable flows in which an SLHelper process is started include:

  • BPA executions.

  • GQI query executions when the GQI DxM is not enabled.
