We are on 7.5 patch 1.
Curiously when I went into nmmgr yesterday, I found store and forward set to 1 (enable), which not done intentionally. Last week I had occasion to add a new subnet to the gateway list, and do an update on the network config - maybe Thursday or Friday, so is it possible that this could have chewed up buffers to produce the result we saw yesterday? Even more curiously, we had almost exactly the same event start on Aug 19 ( a Sat) in 2006...... found some mails in my 3000 folder on it.
thanks,
John

Opps, I missed that part.
One thought, are you sure you have all the latest OS, specifically network patches?
And can you post the TCP setting page from NMMGR?

Craig,
Maybe I didn't send you data from before reboot, but connections was at ~4050, and climbed whenever anybody logged on, or I tried to startspool a device with spool files waiting. But I was getting sockerr 131 , exceeded max connections immediately after doing a startspool on a problem printer, and co0uldnt get sessions above 165.....the 109 is after the boot.
Now at 193 sessions, and tcpglobal shows 248 connections - a fair bit of jdbc going on.....Yes 1024 should be enough, but how do I find out who stole the rest before, or when it happens again.???
thanks,
John
John,
What makes you think you are soaking up the ports?
I don't see anything indicating you are using more than 109.
Resets do seem to be an issue, but I am not sure why.
Are you pre-allocating virtual terminals?
NSCONTROL STATUS, will show you what you have.
NSCONTROL START;SERVER=VTSERVER,min,max
Will set the min and max, so if your high count is 260 user, then set min and max to 260.
If your license count is 384, set them to 384, that way the connections will be there when you need them. Plus you won't have the overhead of process creation/deletion.

please be picky, I need all the help I can get. I know it shouldn't be that high. This same identical event occurred LAST year, Aug 19 to be exact. What else could soak up all the connection table entries?
We usually peak at ~260 sees, 50-60 jobs. Today we couldn't get sess past 165, and several printers would not startspool, as they immediately gave the error msg.
Was suggested something was either scanning ports, or clogging with started but unacknowledged txs.....
thanks,
John
John,
Not to be picky, but I don't think number of connections is the issue.
for only 80 session 1024 should be plenty.

John,
From the data below, your system looks ok. The highwater marks are just that, highwater marks, but yours are not high enough for concern.
You may want to check for broadcasts,
LINKCONTROL @,a,
And post it here.

7.5, N SERIES, 3GB RAM, PROBLEM WASN'T THERE last Friday.
JDBC connections to Image , but have been doing these a long time without issues.
Recently installed MS Exchange server 2003 (a week ago), no apparent connection, but....
currently 166 sessions, 32 jobs, has been a lot higher without issues before. Happened earlier today, stopped/started network, seemed to clear....
nettool shows some data but why not the high water marks?
