Web page Access = System Crash?

I have a NET-50 based device that works fine on the LAN that it was developed on. The AWS web pages can be accessed at any time without fail. On our customer’s network however, the web page access works fine for a few minutes, but then crashes the system. If the web page is not accessed, the system will work indefinitely. Does anyone have any thoughts? Regards, James Fegan Engineer

Do you use the same board wit the same amount of memory ? try load the code with the debugger on the customer site, place breakpoints at the exception handlers and wwait until you hit one of them. Then try to backtrace to the part of code that does it.
