We are using win2k as, all libs compiled with fdset 1024. So every instance of call signal calling thread call do the select of maximum 1024 sockets. >From the other hand, we use Dual Pentium Processor(r) platform, so we can operate more than one thread at one time. ( say, two threads ;) So, we use CallSignalHandlerNumber=2. As a result we have 1024 * 2 signal channels can be served. -----Original Message----- From: "P. P."
