Hi Team,
 
I am facing tsm/ve backups hung  over some couple of weeks which is 
requiring manual intervention to reboot the datamover server then only I 
am able to get the backup sessions running fine.

share your experience and fixes if any you come across for this issue

tsm/ve version 7140
platform windows 2012
tsm server version  7.1.4.100

I do not find any errors in error log for the hungs when we had traces 
enabled so disabled them then the error log saying as below 


dsmerror.VE_POK11DM3.log
