socket_write() never returns? - <b>MY ANSWER</b> - Yes, Program execution suspended on
socket_write and hags up.
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 .

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.

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?

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.
