Gateway restarting on its own again and again

I have an application developed on iPlanet Application Server, integrated with the Portal using URLScraper. I am running the Application through the Gateway. The gateway is restarting on its own time and again and I have to log in again every time. At times the gateway restarts after 5 - 10 mins...At times, it goes on for 2 - 3 hours. Also, even when the gateway does not restart, I am shown the Portal Authentication menu page while working on the application. Apparently, something is happening to the session or to the gateway.

In iwtSession, I found that a lot of sessions were being created and some were destroyed with 5 -10 minutes of being created, while only 1 person was working on the Portal. Could this be the problem?

What all could be the reasons why a gateway would restart on its own? I have set the maximum idle time of the session to 30 mins. and the max session time to 800 minutes.

The session are not set on the gateway but rather on the server. The gateway itself has a session with the server. The gateway restarts if it looses its session with the servers or if something else happens that forces the gateway to restart itself.

Take a look at the web server error logs to see if the web server is restarting during the time the gateway is restarting. You can see this at /install_dir/netscape/server4/https-hostname/logs

Also the additional log information that would be usefull here is the iwtGateway, take a look at that, at the time of restart. Make sure ips.debug=message when you look at the log files.

What version of portal are u using ips sp3a ?
