High CPU Usage by ldapIF (Doc ID 2372677.1)

Last updated on JULY 20, 2018

Applies to:

Oracle Communications Network Charging and Control - Version 12.0.0.0.0 to 12.0.0.0.0 [Release 12.0.0]
Information in this document applies to any platform.

Symptoms

On Oracle Communications Network Charging and Control (OCNCC or NCC) and Oracle Communications Convergent Charging Controller (OC3C or 3C) release 12.0.0.0, the Data Access Pack (DAP) module now has the ability to look up Lightweight Directory Access Protocol (LDAP) services.

In order to achieve this, a new process, ldapIF, was built which is called by the DAP Request Feature Node (FN) when a request is to be sent over the LDAP protocol (please see the DAP User and Technical Guide for more information).

When the ldapIF process starts as part of the Service Logic Execution Environment (SLEE), it hogs 100% of a CPU even when it is not handling any requests.

Changes

Installation of NCC or 3C 12.0.0.0.
