XMC 4500 Ethernet failure

Hello everybody,

I'm using the XMC4500 Relax Kit and I have the following problem:

I send UDP packets to a client in a while loop. Now my problem: If i disable the IRQ for ETH0_0_IRQn, the xmc is sending infinetly. But if i don't disable it, the xmc end sending the packets after about 1427000. Also it happen, if i disable the IRQ before sending and enable the IRQ after sending packets.
i use the library -> lwip. i also use in the while loop the housekeeping function -> sys_check_timeouts().
i'm using DAVE4 in the latest version.

perhaps anybody can help me.
