OS crash on Mac using any recent FileZilla build

[stevepodradchik]

For > 1 year, loading a directory list causes a crash in Mac OS. Installed multiple OS updates, multiple FileZilla updates, etc. Crash generally happens on directory listing but sometimes takes opening a few directories before the crash happens. I would also note that NO OTHER APP causes anything like this and I am a software developer so please do not blame the OS -- just workaround any OS issue if there is one. Very, very easy to repro. Let me know if you need more info but I think the Mac version, Mac OS version, and FileZilla version are included here. The only 3rd party kexts is the Forinet security/VPN client and .. no .. removing it does NOT make any difference (tried that).

That's your problem. The fortinet snake oil is rancid. Please uninstall this placebo and hire a real doctor.

[stevepodradchik]

Wow! Thanks for being a complete jerk. You apparently missed the part about removing FortiNet did NOT resolve the issue. Do you ever get out in the real world and talk to humans?

Rather, I'm uninstalling FileZilla from all our corporate machines and using an app that works and doesn't have people like you maintaining it.

Steve

[Tim Kosse]

According to the crash log the FortiNet kernel extension is still loaded, it has not been removed.

[stevepodradchik]

Correct. I put it back in because I need it for a work VPN and removing it has NOT made any difference in the past (and it's a bit of a pain to put back once removed).

If I remove it and still get the crash, will you or someone look at the bug and not close it out of hand?

Thanks, Steve

[Tim Kosse]

I can have a look at the clean dump, though I won't be able to do anything with it.

A fundamental design aspect of modern operating system is process separation to prevent one process from crashing the entire system. In your case, FileZilla does something that crashes your entire system. This means that there must be an underlying fault in your system (be it kernel, drivers or hardware) that results in this this design principle violation.

The most common cause for system crashes are faulty third-party drivers and kernel extensions. Nearly all reported system crashes show at least one loaded third-party kernel extension, making them the most likely culprit.

Analyzing MacOS crashes is Apple's responsibility, you need to contact them. They'll probably ask you to remove all third-party kernel extensions, if they reply at all. If the problem then goes away if not using any third-party kernel extensions then it must be reported to the kerel extension vendor.

That said, the fortinet kernel extensions are known to be highly problematic and a leading cause for MacOS system crashes.
