Gateway service restart on AIX

Due to heavy load generated by TDMS_RFCs the gateway service on PRD CI hanged due to that there were many spool errors.
Solution
1. Logged on to CI
2. Found gateway service
ps -ef grep gw
found the process named gwrd (this is gateway service on AIX)
3. Killed the process with command
kill -2 PID of gateway service
4. ps -ef grep gw
again
it will show new gwrd process running.
(Actually dispatcher automatically restarts the gateway once it is killed)
