Customer Detected :    RNGD process running and consuming high CPU

 

Cause

rngd process consuming high CPU

Environment

Release : 14.2

Component : CA IDENTITY SUITE (VIRTUAL APPLIANCE)

Resolution

1. RNGD service is disabled in Vapp 14.2 and 14.3 latest cumulative patches.

2.  The Random Number Generator (RNGD) service used for setting up the entropy on the Virtual Appliance. 

3. It has been observed that the RNGD service consumes excessive CPU thus impacting the other services on the Virtual Appliance. 

4. The RNGD service is now disabled and services like JCS are modified to run without the help of RNGD, using /dev/urandom.
