Issue/Introduction

We just upgraded to Spectrum 22.2.7 / 22.2.8  and when we try to email alarm details it fails. This is happening on all OneClicks, where they worked before.

SPC-OCC-10265 An internal web server error occurred. See the log file on the web server for details.

An error similar to the following is seen in the $SPECROOT/tomcat/logs/catalina.out as well:

Environment

All supported DX NetOps Spectrum releases 22.2.9 and earlier

Cause

The class "DataHandler" exists in more than one jar which causes the issue. A 3rd party library is causing the conflict.

Resolution

This is resolved starting with the 22.2.10 release. Upgrade to the latest releases to obtain a fix.

Resolved by engineering via defect ID DE566161.

The issue was reproducible in Broadcom labs using RH Linux systems. It was not reproducible on Windows.

There is a workaround:

  • On the OneClick server remove the mail.jar file from the $SPECROOT/tomcat/lib directory.
    • Delete it or move it outside of the $SPECROOT directory.
  • Restart the Spectrum tomcat web server service.
  • After the tomcat restart test the email send to validate it's resolved.
