On Solaris, you can configure the size of the pool used to handle outstanding connection requests. When the server is very busy, all available threads may be in use when a connect request arrives. These pending connect requests are pooled until they can be handled. If the pool size is too small, client connection requests may time out before the server can handle the request.
You can configure different request pool sizes for different protocols. For example, if the server is handling mostly HTTP requests, you can increase the request pool size for the HTTP listener while leaving the IIOP request pool size at a low value.
Values must be a positive integer less than or equal to 4096. If this property is not set, the default is 128. Values greater than 4096 are truncated to 4096 to avoid excessive memory allocation at start-up.
The connection request pool size affects the server memory requirements:
mem = entries * 20K
That is, each entry requires about 20K of memory reserved at server start-up.
