phone reboots during backup (can't use with large sized apps)

[mailinglists35]

I started backing up a long list of apps via screen.

ssh connection is dropped, springboard has crashed and never returns to lockscreen.

I believe this is due to high cpu usage to which iOS tries to respond with respringing.

The next time I'll run with nice (now I can't even touch it until it finishes, ssh connections are rejected, it only replies to ping) but maybe there could be some improvement in the ipainstaller itself?

[mailinglists35]

oh, it eventually rebooted. trying again, let's see if nice makes a difference.

[mailinglists35]

ok, better, no more watchdog timeouts, resprings and reboots. I hope I'll remember to run it with nice -n 19 next time.

[mailinglists35]

a second run caused ios to restart springboard when backing up a large app + data (200Mb size) even with nice -n 19. then it rebooted in the middle of running.
I've got no other idea what to do.

[mailinglists35]

@autopear what would you suggest? Can you optimize some things? at first ipainstaller looked like a great tool, but these problems keep me from actually being able to use it.

[mailinglists35]

perhaps you could implement a smarter less memory-intensive compression method?
this seems to also be an issue:
