NML aborts for different databases

How are you generating those debugs. Try your cfg file NSR_DEBUG_LEVEL & NSR_DEBUG_FILE parameters and run atleast a debug level 3 backup. Post the result here, we might be able to help.

Mostly debug level 3 generates sufficient errors and should be suitable to begin with.

Are there any network issue (check netstat stats). One thing I would try would be to install demo server on Notes box and have backup without network involved - just to rule out network as an issue.

However, if these aborts are caused out of blue without any ROC errors then I would focus on Domino side and have Domino running in debug (which Domino admin won't like for sure). If you see aborted message given to module it means Notes API has returned that.

In the config file we specified NSR_DEBUG_LEVEL=5 and NSR_DEBUG_FILE
but not debug was generated.

You need to tell the file name Sir. Check this:

NSR_DEBUG_LEVEL = 3
NSR_DEBUG_FILE = "C:\bkp_log.txt"

This will generate c:\bkp_log.txt on the client.
