"Interrupted system call"

Hi
After upgrading the perl from 5.6.1 to 5.8.7., accept() function in one of server is failing many times with the error message "Interrupted system call".
Could anyone explain the reason for receiving this error signal continuously.
Please help us out from this problem
Thanks in Advance
Anju.

Are you running on Win32? If so, this and/or this may help you. If not, you'd best post some code plus information about your set-up: Perl version, OS etc. Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal? "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply] [d/l]

For background on this change see http://perldoc.perl.org/perlipc.html#Deferred-Signals-(Safe-Signals). I'd guess you are getting SIGCHLD. Two easy things to do: you can either turn off safe signals as described, or put a loop around your accept that ends when it succeeds or gets an error other than EINTR.	[reply]
