 Posted: Thu Aug 25, 2011 2:05 pm Post subject: SNPP server - Too many active sessions |
 |
|
I have been getting the following message from the PageGate SNPP server -
450 Too Many Active SNPP Sessions. Please Try Again Later
The server seems to recover on its own after a while. I would have thought this error was the result of high traffic, but the server is only getting maybe 10 pages per minute at most.
I would like to try reducing the timeout time for idle sessions. Is this possible?

| Do you have something (or some things) that are connecting and staying idle instead of dropping the connection? The reason I ask is that the message you're receiving is telling whatever is trying to connect that all available communication paths are currently busy and to please try again later. Now, PageGate's SNPP server can accept more than one connection at a time, so you shouldn't see this message unless you have multiple things all trying to connect at once... or if you have something that's connecting and just sitting on the open connection, leaving one less thing for other systems to use. Then if you have two things doing that, it only leaves one open avenue... and if something tries to connect while the only open port is actively being used, that would spawn the message. |

I suspected something like that might be happening. I'll try to identify the culprit, but in the meantime I thought a very short inactivity timeout on the server might allow it to release the idle connections quickly enough that it wouldn't run out of sessions.
How many simultaneous sessions can the server support? Is there a parameter that can be set in snpp.ini to control the timeout?

The PageGate SNPP server supports 20 simultaneous inbound SNPP sessions. It would have to be a very busy server to reach that limit (each session typically only takes a few seconds).
Now, we could try increasing that but I'm fairly certain you would probably have same problem, as we would be trying to fix the symptom, but not the problem. You might want to speak with your firewall people as it might be better handled at the firewall level. |
