Avamar 7.3.0-226 integrated with VMware 5.5.0, deployed one proxy using Proxy Deployment manager - can see all the clients from with the vCenter however, some clients backup no problem, others fail with the error 10054 in the Activity log and then when you open the session log you see:

avvcbimage Error <0000>: No response from Avamar Administrator to retain snapshot request, (Log#1)

avvcbimage Error <0000>: createSnapshot: snapshot creation or pre/post snapshpt script failed (Log#1)

avvcbimage Error <0000>: createSnapshot: snapshot creation/pre-script/post-script failed (Log#1)

Have checked the datastores that the proxy is able to access and all those seem correct. Interestingly, the clients are part of a large scheduled group and when I come in the morning and run an on demand backup of some of the failed clients, some complete!!!!! and some continue to fail!!!!!!

Any assistance would be appreciated
