If the problem still persists on recent PHP versions, we need reproduce code or at least a backtrace.

It's really just a call to write(3) so there's not much room for it to have problems. Could the socket be blocked - <b>MY ANSWER</b> - Not sure, it may block by php function and have a some dead lock situation. implying the client isn't reading everything from it? - <b>MY ANSWER</b> - client is reading all information when it is delivered . ------------------------------------------------------------------------ [2014-01-27 06:36:45] jitesh dot prajapati at infostretch dot com Thank you for your quick response. Please find following URL containing code we have implemented. http://202.131.96.147/test/wevsocketclass.php Execution got suspended on "socket_write" function in "send" method, and till i do not restart service it hangs up. We do not implement explicit block/unblock of sockets. We have tried on different linux servers, and same issue is producing on each servers. ------------------------------------------------------------------------ [2014-01-26 00:04:13] requinix@php.net Still not enough info. We need to see demo code (a short sample that exhibits the same problem, not your real thing), or error information, or backtraces, or something. A textual description of what you observe is alright but doesn't really offer us much to go on. You say "crash" but the process is running? Then it's not a crash. socket_write() never returns? It's really just a call to write(3) so there's not much room for it to have problems. Could the socket be blocked, implying the client isn't reading everything from it? ------------------------------------------------------------------------ [2014-01-25 10:41:22] jitesh dot prajapati at infostretch dot com More Information ----------------- We have implemented web socket server, and it is working fine, it able to handle so many read/writes. Now issue is after some time (around 20-30 mins and sometime longer than it), server got crash, it shows service in process list but server does not able to request response. We have placed different debugging points and found that server goes crash on executing function socket_write. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
