so during 2 minutes g-wan loops , after g-wan started monit believe. have explanation , workaround?

i change web hosting provider , use vm under microsoft hyper-v. problem remains: g-wan restarted monit logged following events:

wed, 16 oct 2013 02:02:12: process pid changed 2171 20631 wed, 16 oct 2013 02:02:13: process ppid changed 1 2171 wed, 16 oct 2013 02:02:43: process pid changed 20631 20975 wed, 16 oct 2013 02:03:13: process pid changed 20975 21318 wed, 16 oct 2013 02:03:44: process pid changed 21318 21573 wed, 16 oct 2013 02:04:14: process pid changed 21573 2171 wed, 16 oct 2013 02:04:14: process ppid changed 2171 1 wed, 16 oct 2013 02:33:06: process not running wed, 16 oct 2013 02:33:37: process running pid 776

it happens every day on new vm hypervisor.

i not 1 behavior. have explanation , workaround?

thank jerome

the loop means child process not responding, hence parent killing old child , restarting new child.

could email whole log files (trace , gwan.log)? partial post missing the informative parts.

update

that new problem 4-years old code worked fine far platform issue, have found workaround, published next release in few weeks.

android - getbluetoothservice() called with no bluetoothmanagercallback -

i getting getbluetoothservice() called no bluetoothmanagercallback error in android application. i have no idea causing or bluetooth manager callbacks. can give me idea of causing problem or start looking. by reading android source code, seems warning cannot about. source code shows if call bluetoothsocket#connect(); then call bluetoothadapter.getdefaultadapter().getbluetoothservice(null); the key here, null parameter passes in above line. due this, there no callback, , bluetoothsocket class throw out warning. since warning, not think need it. https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothsocket.java line 306 https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/bluetooth/bluetoothadapter.java line 1610
