I have the awecome problem of every outgoing port being consumed. 1025-5000. 99.5% of them are connecting to a SQL Server of mine.

My latest huncch is that connection pooling is not being used, and the default 4 minutes time_wait wont cut it for 1000's of connections per minute for this website.

Has anyone else seen something similar?

netstat -an looks similar to this.


c:\netstat -an

TCP 10.0.0.1:1025 10.0.0.2:1433 TIME_WAIT
TCP 10.0.0.1:1026 10.0.0.2:1433 TIME_WAIT
...
TCP 10.0.0.1:5000 10.0.0.2:1433 TIME_WAIT

[lsass.exe]


Think I am on the right track? My dev's code is all powerful. Convincing them its wrong is not easy.

I have successfully proven there is something odd in the code of this website. (I stopped it and the time_waits all went away)
Started it and they all came back after a minute or so.


My inclination is connection pooling is not working. Unfortunatly for me, this is now an asp question.
