Error description
The backup performance for NAS backups with the TOC=YES or TOC=PREFERRED keyword might be severely degraded using a Tivoli Storage Manager V6 server. If you think you are facing the symptom, a server instrumentation trace will show a highly active AfStoreRemoteThread. For help setting up this trace please contact your support representative. In the example below, about the whole time the trace was collected (03:54:49.177-->04:18:04.584) the thread was fetching information from DB2.

This issue also applies to filer- to-server configurations in which images are stored in a native storage pool. If this is the case, the thread in question will be the AfStoreNativeThread instead of the AfStoreRemoteThread.
