Archive Manager crashing after upgrading Spectrum to 22.2.6 or 22.2.8 versions

Products

• CA Spectrum
• DX NetOps

Issue/Introduction

After upgrading to DX NetOPS Spectrum to version 22.2.8, the Archive Manager is crashing with a core file. 

 

 

 

Environment

Release : 22.2.x

Cause

By now, this problem was only observed in Spectrum 22.2.6 and 22.2.8 versions.

In this case, there were some "FLATFILE_EVENTS" parameters configured in $SPECROOT/SS/DDM/.configrc file, similar as the ones below:

FLATFILE_EVENTS_FILENAME=/ca/backups/event_integration/spectrum_events.log
FLATFILE_EVENTS_MAX_FILESIZE=1024
FLATFILE_EVENTS_BACKED_UP_FILECOUNT=5

These parameters are used when customer wants to export the Spectrum events to a flat file (in the above case, spectrum_events.log")  in order to be consumed by third-party tools.

In addition, the following error was seen in the core file generated:

*** Error in `/ca/spectrum/SS/DDM/ArchMgr': corrupted double-linked list: 0x00007f6794043880 ***

Resolution

Spectrum 22.2.6 and 22.2.8 only:
==========================

1- Please contact the Broadcom Support team and ask for the respective patch to be provided:

22.2.6 : Spectrum_22.02.06.D196
22.2.8 :  22.2.8_PTF_22.2.801

2- Execute the following procedure:

----------------------------------------------------

The patch must be applied in the Spectroserver only. After applying the patch, and before starting processd and spectroserver, please edit the $SPECROOT/SS/DDM/.configrc file as below:

a- Uncomment the "FLATFILE_EVENTS" lines (if commented). i.e:

FLATFILE_EVENTS_FILENAME=/ca/backups/event_integration/spectrum_events
FLATFILE_EVENTS_MAX_FILESIZE=500
FLATFILE_EVENTS_BACKED_UP_FILECOUNT=5

b- Insert the new parameter (provided by the patch):

FLATFILE_SKIP_PERF_EVENTS=TRUE

P.S: System generates a huge number of performance events ( "modelTypeName": "SSPerformance" ) which will be used by perfCollector tool. At present these performance events are also written to flat files.
By using FLATFILE_SKIP_PERF_EVENTS=TRUE option, the performance events will not be written to the flat file.

3- Save the file, and proceed with the processd and Spectroserver start.

----------------------------------------------------

Spectrum 22.2.5 (and lower), 22.2.7 or 22.2.9:
================================

(workaround): Comment out the FLATFILE_EVENTS lines in /ca/spectrum/SS/DDM/.configrc, and restart Archive Manager. This will prevent Archive Manager from crashing.

 

This issue will be addressed in future release of Spectrum.
