Hi Daniel, Thanks for the response.
We are not using the pike module. The requests to a port are not dismissed; rather, in most cases, there is a delay in response from kamailio. Also, the delay is not restricted to any particular message request. it happens for any type of request. (register; subscribe; etc...). But those same requests, if pointed to different port, have no issues. Also, to note, I am not restarting kamailio when the issue occurs on a particular port. kamailio is kept running and pointing traffic to a non-problematic port seems fine.
