I have used msgrcv() in my source to receive messages in a while(1). But it returned an error in errno 514(ERESTARTNOHAND). I search this error in net, and it seems to be should not happen in user program. But it happened in my program, and once only. I didn’t see it happens after that once. My question is how can I make this error happen again? And how can I fix it? I saw RedHat has fixed the problem, but no details on their website. My OS is Montavista 5.0(Kernel2.6.18). Thanks
