Generally, if you get a "Address and port already in use" and you know
that no other service or program uses that address/port then you have a
hanging process that hasn't shut down property. Check the Task Manager
to see if the process is still running if it happens again. If it
interacts with IIS then restarting that can clear it too (it may be that
an ISAPI DLL is hung up if you are interacting with one).
My only guess as to the resources problem would be that it may be file
handles it is running out of (since each TCP connection uses a file handle).
Either way it sounds like a connection or connections are not
terminating correctly and leaving something hanging - possibly over and
over, thereby eating up file handles.

Panicing here a bit. Have a service running under windows XP that does two
things.
First it runs an Indy TCPServer. Uses this for communication with remote
control apps.
Second, it runs manages a bunch a extremely cpu intensive processes,
starting them and stopping them as requested. It does this largely so
console application (written in fortran) can be started on machine startup
and run in background.
Now, first indicartion of problem was when got error from service as it
tried to start these processes.
System error - insufficient resources etc.
hmm. Not a memory problem. pretty of main memory, memory usage by
the service unchanging and small. Stop service, uninstall, install, start.
Fails to start. This time the event log says TCP Server failed to start -
"Address and port already in use". Say what?? The server was uninstalled.
Anyone know why address and port might be tied up. I have stopped and
started the service many many times without problems. Had to reboot in the
end.
The out of resources. What a strategy for finding out what resources its out
of? Does writing output to a filestream opened on "NL:" actually consume
any resource??
Any ideas welcome.
