No worries – thanks Ray
After testing for a week or so it seems to hang at odd intervals every two to three days. Working hypothesis for whats causing the issue is either:
1) buffer overrun – I’d opened port 8080 to the internet so wondering if the input was being flooded occasionally? (i.e. port scanners, malware etc) – have closed it now to see if makes any difference
2) slow memory leak (sigh)
Will look at some diagnostics when I get a chance , however in the meantime a watchdog will do the trick to keep it running
In fairness – porting to the W5100 ethernet is just a bit of fun to reuse what I had…. wouldn’t be recommending to do it this way if you were staring from scratch (just order an opensprinkler! 😀 )
Cheers
