Socket permission issue

[Laurent Menase]

your program looks ok, so things need to be look on server side,
- tusc from start is probably difficult


Also is it the first time you start your program that it fails or is it after some time?



You would probably gain some time contacting hp support. - some internal private tools can give informations about listening socket status.

[Laurent Menase]

in fact it can happen also if the listen queue of the server process is full, or if the server called shutdown() over the listening socket.

Thanks Laurent,

there is a part of the tusc as follow, can the unlik be the cause?

Thanks

[Laurent Menase]

no the unlink() is there to remove any remaining socket fil before binding and recreate the socket file - else bind would fail

in fact you need to look for syscalls call on fd=12

[Laurent Menase]

Finally how did it end up ? Did you find the solution?
