Re: ports not releasing

We are having a problem with our recharge_agent process. When it
terminates abnormally the ports that were in use by this process are
left open and listening, so when we attempt to restart the process it
dies almost imediately because the specified ports are already in use.
Apparently the UNIX Kernel is not releasing the ports once the process
dies, so my question to you would be . Can these ports be released
without rebooting the server???

Below are the ports that we use for this process.



sdp_rech_agent_port=18001

sdp_rech_agent_telnet_port=18002

sdp_query_agent_port=18003

sdp_query_agent_telnet_port=18004
What "Unix" are you using?
Try lsof to bring out Information about what processes are on your open Ports.
# lsof -i:18001

Then try to kill the Processes that are using these Ports.

Example from my machine:
<snip>
# lsof -i:25
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
sendmail 155690 root 7u IPv4 0xf10000f300385b58 0t0 TCP *:smtp
(LISTEN)
<snip>
