After more investigations, it look like each of this Wrote stack traces" logcat line will write a /data/anr/slow??.txt :
shell@android:/data/anr $ ls slow00.txt slow01.txt slow02.txt slow03.txt slow04.txt slow05.txt slow06.txt slow07.txt slow08.txt slow09.txt traces.txt My question to thows in the know is - can it be disabled ? I had high hope in a property called dalvik.vm.lockprof.threshold set to 500 but chaning it or removing it doesn't do anything. - who thought that this "feature" to write stack traces if the UI thread is blocked for 500ms is a good idea ? Is it to make the device even slower, writing stack trace that nobody will ever read ? This "feature" seems to be only be enabled on some ROMs but doesn't look restricted to CyanogenMod.
