multi-threaded socket communication problem
Hi there,
In my app, I need to open many threads which all connect to a same server and same port, reading and writing data at the same time. But the problem is that after some time of execution, I got error something like "ESocketError: maximum number of sockets allowed....", it seems that if there's too many threads(actually over 10 or so), then it won't let me connect.
I use TClientSocket to do the socket communication. So i'd like to ask why I am getting this error? Is there any limit on number of threads connecting to a same server and port number?
Thanks for any input.

What OS are you running on? Is the server on the same machine as the client?
ASKER
i am running on Win2k, no, the server is a remote one, actually it's a mail server. I used tcp/ip to make a direct connection to it. If i use only 1 thread, it works alright, but if I use many threads, i always got that error.

are you creating thos sockets connection dynamicly? if the answer is yes... then... did you realease each one of them?
"ESocketError: maximum number of sockets allowed" sounds more a local problem than a server problem, however what kind of server are you connecting to (email, web, or custom)
