I have an SSL server, which has, suddenly stopped processing client requests. I see the following error. >> SSL_GET_NEW_SESSION:ssl session id callback failed. Exactly after 15 seconds of calling SSL_accept, the error is seen. The socket is non-blocking. The application was running fine for about 10 days. The problem started suddenly and thereafter, each and every call fails with the above error. And each time it is 15 seconds. The application has 20 worker threads and one epoll thread which handles data and hands it over to worker threads for processing. The epoll thread gets client-hello, notifies the worker thread which calls SSL_accept. Any thoughts on why SSL_accept would not return even if socket is non-blocking. -Prabhu.S -------------- next part -------------- An HTML attachment was scrubbed...
