Products

• CA Identity Suite
• CA Identity Manager

Issue/Introduction

During Provisioning Servers startup, entry errno=10048 (WSAEADDRINUSE) is seen in im_ps.log file. This error did not happen to all imps machines, and the provisioning server functioned properly.  What is the root cause of it?

Environment

CA Identity Manager 14.x

Cause

This was due to both localhost and hostname binding to the same ports 20389 and 20390 based on the registry setting.

Resolution

This is a false alarm, and it can be ignored.  However, the error can be removed by enabling IPV6.
