Hi<br />
<br />
We use Websphere 5.1.1.5 on Windows 2003 platform.<br />
<br />
We have servlet based applications running on that. External client applications post documents to various Urls which inturn map to specific Servlets running within the Appserver.<br />
<br />
The front end is IBM HTTPServer 2.0.47 running on Windows 2003. The WAS plugin routes the info to this appserver.<br />
<br />
The get random Read Timeout errors in these servlets.<br />
<br />
Daily there are in excess of 50,0000 posts to these Application. The read timeouts occur about 60-70 times in a day.<br />
<br />
The error details are:<br />
<br />
<hr />
<br />
java.net.SocketTimeoutException: Read timed out<br />

There may not be anything you can do about this. If someone's browser is
connected via a very slow connection, you'll see these errors.
