Hi!
I'm running a simple TCP-Webserver on the T4.1 with the NativeEthernet Library.
From time to time i encounter this weird Exception (using CrashReport):
A problem occurred at (system time) 9:4:43
Code was executing from address 0xAAE0
CFSR: 82
(DACCVIOL) Data Access Violation
(MMARVALID) Accessed Address: 0x14 (nullptr)
Check code at 0xAAE0 - very likely a bug!
Run "addr2line -e mysketch.ino.elf 0xAAE0" for filename & line number.
Temperature inside the chip was 53.82 °C
Startup CPU clock speed is 600MHz
Reboot was caused by auto reboot after fault or bad interrupt detected
Has anyone of you encountered this problem too?
I was able to pin down the corresponding lines, which cause these issues:
&
I initialize my Server with the following lines of code... the rest of the code is pretty much just the usual stuff, like in the examples...
Does anyone have the same problem, with memory caused lockups from time to time?
Anyways, thanks for anyone who could have a clue on that topic.

Code:
setMAC(mac); Ethernet.setStackHeap(1024 * 64); Ethernet.setSocketSize(1024 * 32); Ethernet.setSocketNum(6);
Ethernet.setRetransmissionTimeout(10); Ethernet.setRetransmissionCount(2); Ethernet.begin(mac, ip, dns, gateway, subnet);
server.begin();
