Are you using signals? Take a look at sigaction with a flag
of SA_RESTART.

Any function that can return an EINTR should be coded to handle
it appropriately which usually means do the call again.

System calls can usually fail due to "EINTR"; if you yourself handle
and/or generate signals, you need to make sure the signal handler
is iunstalled in such a manner that the system call is restarted.

I.e., use sigaction, use SA_RESTART; do not use signal().
