Symptoms

Avamar garbage collection fails with the following error: 

Last GC: finished Fri May 22 12:25:36 2015 after 52m 16s >> recovered 0.00 KB (MSG_ERR_DUPLICATE) 
 

Cause

Garbage collection was started more than once within a short time.

 

This can be verified by sending the output of theGC maintenance logs to a file and reviewing the contents:

dumpmaintlogs --types=gc --days=5 > gc-maint.log.`date +%y%m%d`
 

The following maintenance log extract shows a second garbage collection job issued within 15 minutes of an existing job:
