One of my gateways occasionally decides to stop running. This is the error I see when doing a 'wep <epname> status' is :

The remote client was not created.
ipc_create_new_remote_client failed: unable to connect to
172.20.44.50+9495: (6) FRWOG0046E out of file descriptors. ; Endpoint may not be running

The gateway is AIX 4.3.3 and I am running Framework 3.7.1 patched to 74. I do not see anything in the oservlog or in the gatelog that would help, is it more an AIX setting? If I issue a wgateway <gatewayname> stop/start, it will work normally.

"Out of file descriptors" is your clue to the cause of your problem. The gateway uses RPC threads to initiate all method calls. An RPC thread uses a file descriptor, if there are no more file descriptors, then the method cannot be run.

Check the OS file descriptor value and I would also suggest changing the 'logstatus_interval' on the gateway to 300 seconds, so that you can get more information about the activities of the gateway.

I had put a script called 'gw_monitor_v1.1.pl' on the ftp site (testcase). This will give you the logstatus of all your gateways, as well as the "odstat -c", to see current running methods. The script may still be out there.

There is also the Endpoint Gateway Internals Field Guide that will help you understand how the gateway works, and how it uses resources.
