Hi Leena,
Do you have a firewall between the two DCs? If yes, connection
reset can be caused by Cassandra trying to use a TCP connection which is
already closed by the firewall. Please make sure that you set high connection
timeout at firewall. Also, make sure your servers are not overloaded.
good on all nodes.

Hi Leena,
First thing you should be concerned about is : Why the repair -pr operation
doesnt complete ?
Second comes the question : Which repair option is best?
One probable cause of stuck repairs is : if the firewall between DCs is closing
TCP connections and Cassandra is trying to use such
marked either ways).

for repairing nodes on a regular basis with multiple datacenters involved.
We are running cassandra 3.7 in multi datacenter with 4 nodes in each data
center. We are trying to run repairs every other night to keep
