I have a piece of coode which does some networking, in which I see read and write calls failing with 'Interrupted system call' from time to time.
The reason it puzzles me is that I am explicitly catching every signal that could possibly be causing this, with the SA_RESTART flag set. So surely I should never see this ? This only started happening when we moved away from 4.11 - it was happening the whole time I was running on 5.4 and still happens on 6.0. I thought that the default was for restartable system calls - I only started setting the SA_RESTART flag explicitly in the last 24 hours in an effort to fix this, but it is still happening. Have I missed something fundamental about signals and system calls ? I am about to go in and adapt my code so that it retries the system call if it is interrupted - but I am uneasy about doing this without knowing *why* the system calls arent't restarting automaticly. -pcf. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
