SIGPIPE if socket is full

[Johann Fischer]

our print application get a SIGPIPE signal after 3 minutes if the socket is full on HP-UX 11.11. The connection is still established and the printer send a TIMED package each 15 seconds but the application hangs in a write system call. After receiving the SIGPIPE signal we suppose the connection was broken. Is there any timer in the tcp system to modify such a behaviour?

Hi

the ndd command shows no parameter which is related to a socket timeout. There are some description in /usr/include/sys/socket.h and socketvar.h but I don't know the value.
socket.h:#define SO_SNDTIMEO 0x1005 /* send timeout */

socketvar.h: short so_snd_timeo; /* send timeout (not used yet) */

Problem was outside of HP-UX software
