Sorry for disturbing. A simple reset of DMA solved the problem. Now I'm searching why....

I'm using MCBSTR9 running eCos and lwIP-Stack. I use the Socket-API of lwIP to send a small web page on a request. The problem I have is following: The stack starts normally and manages to receive and send packets (you get the web page by request). But after some time (it varies how long) the MCU doesn't run the TCP-ISR anymore and only the idle thread is executed. The stack is executed with enabled debug support but I get no further information. The only thing I can imagine is that the TCP-DSR disables the TCP-interrupt and is somehow prevented from enabling it. Is there a way to find out where the TCP-ISR is disabled?? Or is there another possible occasion for this bug??
