RT application freezes/hangs occasionally when using remote panels

[UlfN]

Hi!
Background:
I have developed an application running on a cRIO. The application have 4-6 parallell processes. Small amount of data is sent to host application over TCP/IP (from 10 to 1000 bytes/s). I'm using remote panels for debugging the system.
Problem:
Occasionally I've noticed that the whole application freezes(the whole application and not only the top level GUI) and when I'm change something on the remote panel(=generate an event)the application countinues. Could it be some TCP/IP problem with remote panels that locks the TCP/IP resources in the application? No error code is generated after the "freeze" so I can't locate the problem.

Hope that someone can help me with this problem!

Regards Ulf

After long time testing (10days):

Everything works fine when I'm not using Remote Panel and the web-server. Seems like NI have some problems with Remote Panels and other background TCP/IP-communication. Could the problem be TCP/IP deadlock?

An alternative to remote panels, which are great for getting applications up and running quickly, is to set up a tcp/ip client on the host side. You might consider these ideas.

Thanks for your reply Mr Johnson,
I've implemented solution that is simular to the one in the article. One difference is that I don't use XML for sending data. The reason I don't use XML is that it consums a "lot" of memory and cpu-power.
