iSecureOS crashing with “Should perform in-depth scan” enabled

[jkole4]

Every time I enable "should perform in-depth scan" iSecureOS crashes. The last thing I see it scanning is /usr/libexec/git-core/git-rebase--preserve-merges. Scanning without it enabled will make it scan successfully and not crash.

Also scanning with tweaks disabled with not do anything  either still crashes

The process was terminated for exceeding jetsam memory limits seems to be indicating that the hashing takes too much memory and jetsam forces the app closed. Will fix.

I too was suffering from this problem. Fortunately I had half a gigabyte of old dependencies which I cleaned through apt-get auto-remove, after which the scan worked with no crash.

Yet even now, the peak of memory usage during a scan was 700mb - dangerously high on a 2gb ram device. It is possible the app os crashing because the device physically cannot allocate any more memory, and just increasing jetsam will lead to springboard crashing instead.

The best way to fix this is to release memory during a scan. Right now it seems memory is released only at the end, which anyone can see will lead to problems like this. Once a file is scanned, there is no need to retain it in memory, and it should be released.
