stability issues after updating the bootloader on a mega2560

-

hi,

i have few arduino megas here updated bootloaders on. after doing ran sketches utilize ethernet library , whole system seems lock after 30-40 seconds of operation requiring manual reset.

originally updated support watch dog timer. running scrips written , tested previous bootloader seems fail.

this happens when connected ethernet , has made connections.

sitting on desk no ethernet connection seem loop endlessly no prob, once can make connection though things hairy , system typically locks within seconds.

again sketch tested number of other mega2560s (running factory bootloader) , day have been running without hitch. suspecting new bootloader culprit.

has else ran similar issues or know of way resolve it?

i updated bootloader in ide 1.0.5 , cant find reference bootloader version number anywhere?

i use stk500v2/stk500boot_v2_mega2560.hex (but not sure if version ive installed or not).

thanks anyones help!
