UIM Data_engine restarts over and over again on RHEL

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

After adding 2000+ new metrics being collected, the data_engine probe is restarting over and over again.  In the logs, the probe appears to function normally, but then starts displaying the following for all metrics:

de: QOS_WIN_PERF_DELTA_DAY [QoSData] - Open - Error: [QoSData] thread_id: 0, error: Open: Can't create TCP/IP socket (24) (errno:2004)

This happens each time the probe starts back up.  After some metrics display this, the probe restarts.

Environment

UIM 20.4
RHEL 7.3

Cause

The open file limit (hard and soft limits) were set to 1024. 

Resolution

After changing the hard and soft open file limits to unlimited, the issue was resolved.  The commands to do this depend upon your flavor of linux.  Please consult your Linux server admin.
