Identifying Cache Application Failures with Coredumps

Overview

On the Peer App System Status Dashboard (Status > Dashboard), you can identify several system stability problems, which may indicate a Cache Application crash, as seen in the image below. The purpose of this article is to help users identify these potential failures by checking available resources.

Failure Identification Methods

• Each application crash generates a core dump file. You will find the core dumps in the following directories:
• For Version 5.X, the core files are located at /opt/pang/bin.
• For Version 6.X, the core files are located at /coredumps.
• You can search the core files using the following statement (e.g., for 5.x):
  find /opt/pang/bin -name core* -print

• To search the core files for a specific period of time, you can follow the example below.
  Example: 5.x system between 2019-10-01 and 2019-12-27:

  touch start_day -d 2019-10-01
  touch end_day -d 2019-12-27
  find /opt/pang/bin -name core* -newer start_day -not -newer end_day
