Link dump for TIME_WAIT netstate state.

Posted by peeterjoot on September 14, 2011

One of the db2 processes, when crashed on purpose (or due to coding error) occasionally hits socket in use errors on reconnect, which shows as the TIME_WAIT state in ‘netstat -n -p -a’ output. I suspect that the code in question may want to use SO_REUSEADDR, to allow the code to force a reconnect on restart.

I’ll have to follow up with the owners of the code in question, although I probably have to figure out how to reproduce this reliably first. I wonder if this has been considered and if there are undesirable side effects to using the SO_REUSEADDR socket option in this code?
