Kind of hard to get strace or gdb working on Android. The Iotivity libraries are currently dynamically loaded when running Crosswalk. If you have any clue about how to get gdb working in that scenario, it would be a life safer :) Regarding the file descriptor, here's its value on 5 consecutive runs: D/IP_SERVER(27242): fd = 141 D/IP_SERVER(27747): fd = 129 D/IP_SERVER(27891): fd = 139 D/IP_SERVER(28079): fd = 139 D/IP_SERVER(28247): fd = 141 Any other tips?
