[srsran-users] ZMQ Address Already in Use Error

[J Giovatto]

Hi

you can try to run the application that is failing with:

strace -f -e trace=network your_application

and look for the system error in the output.

then as root/sudo run:

"netstat -tupan" and look for the application that is using the 
conflicting ip:port pair.
