Hi team,

I am facing this issue while executing mysql db server backup, I can see cvping and all ports are working well, also checked commvault agent are bale to install and connect to the commserve,

Kinldy help

ERROR: cvfwd_iot_wait(): Couldn't issue a zero-length read on fd=23144: Connection reset by peer

Any one knows the rsolution of this?

hello @Ram Chandra 

It seems that the SQL Server might not be on the same subnet as CS, which could explain why connectivity is happening through port 8403. Have you had a chance to check cvfwd.log for more info?

 

other thing go in my mind antivirus the most virus-scanning applications use real-time scanning this may block commvault processes check this link for more details
