Avamar: Checkpoint fails with MSG_ERR_EXCEPTION

All the Avamar services are up and running.

The grid is fully operational.

Avamar checkpoints are failing with error MSG_ERR_EXCEPTION:

avmaint cpstatus

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<cpstatus
  generation-time="1535023554"
  tag="cp.YYYYMMDDHHMMSS"
  status="error"
  stripes-completed="882"
  stripes-total="883"
 start-time="XXXXXXXXXXX"
  end-time="XXXXXXXXXXX"
  result="MSG_ERR_EXCEPTION"
  refcount="1"/>

Both the gsan.log (/data01/cur/gsan.log) and err.log (/data01/cur/err.log) report an error while reading a stripe (Too many links):

Example:

YYYY/MM/DD-HH:MM:SS.SSSSS {0.0} [strtask.2:3205]  <0055> checkpoint cp.YYYYMMDDHHMMSS 560 out of 883 stripes complete
