Why connection disconnect automaticly

hello,

our environment： centos 6.5  flash media server 4.5   juv-client

our problem: We use the long connection built by juv-client between clients and server , and so , different clients can connect eath other by this connection. But we find that this long connection is not reliable. A long connection between a client and server will disconnect automaticly.  Unfortunately, the client can not test this change succesfully and the server dont  always notice the client.

How can we deal this problem?

Thanks
