Subject: msgrcv() errno 514 ERESTARTNOHAND

Hello List：

　I have a problem with msgrcv().

  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
