Browser disk usage issue + occasional kernel panics

[neorgnaic]

I've been having a couple overlapping, possibly related, problems for a few months now.



The first of which is, ostensibly out of nowhere, my browsers (Safari, Chrome, and Firefox - point here being it's not specific to one) started using up HDD space as the cache accumulated site data. Just now as I type this, I've got a single Youtube tab open in the background in Chrome and having it open for maybe 2 minutes ate about 100MB of disk space. Moreover, that number will continually increase until I clear the browser's cache, at which point I do get my HDD space back. I was able to find something of a workaround to this in Firefox (changed something in the about:config page in FF, but sadly don't recall what - it's been a few months now) and thus it has become my primary browser, but I'd still like a proper solution to (or even diagnosis of) this problem. But that leads me to issue #2:



Occasional kernel panics, for which I can't identify a cause. For the last few months, about once a month, a kernel panic occurs, again ostensibly out of nowhere. Each one, as far as I can tell, occurred during something totally mundane. Twice it'd happened while watching some crap on Twitch - a site I use quite frequently - and once while just opening a Reddit tab. I have the panic log from the most recent occurrence, but can't make heads or tails of it:

So yeah, I'm at a loss. Anyone?

Sorry, I have no idea what the browser issue is.

The most useful information in a crash report is usually the process name, but for a kernel panic it’s just:

BSD process name corresponding to current thread: kernel_task

Kernel extensions (kext) could be the culprit. I see that you have paragon software‘s NTFS for Mac installed. As it happens, I have had kernel panics caused by that software. They happened every night during my system back ups. I reported the problem but as far as I know it has not been fixed.

However, it seems quite unlikely that your Mac is accessing an NTFS volume at the time each of your panics occur! I put it out there as an idea, a possible cause.

 

[neorgnaic]

Appreciate the response.

I don't think Paragon is the culprit, unless something about it changed behind the scenes that I'm not aware of. I've had that installed long before these started happening, and there's never been any overlap between the panics and performing backups (which I do manually, anyway).
