In the meanwhile, I made some logs of the statistics/errors directory:
init.log: Directly after "owfs -u1 mnt/1wire"
ok1.log: After starting and stopping "test.sh"
ok2.log: After starting and stopping "test.sh" again.
So far, no errors. Now the critical ones:
on1.log: After switching the mains transformer "ON" (blinking stopped before)
on2.log: After starting and stopping "test.sh" again.
Then I did "killall owfs" and restarted "owfs -u1 mnt/1wire", start test.sh.
off1.log: After switching the mains transformer "OFF" (blinking stopped
before)
off2.log: After starting and stopping "test.sh" again.
off3.log is just a repetition of off2.log after killall owfs and restarting
all again.
I hope you now can find a way to detect this kind of error and automatically
re-initialize.
Kind regards
