My customers keep asking my why they keep having issues with PA-220 disk space on root getting too high.
The first fix was to update from 10.1.1 to 10.1.2-h2, which fixed a bug of a log file not getting cleared.
BUT, even at 10.2.3-h2 I still get issues. Here's a PA-220 in an HA pair going into Non-Functional mode, a mere 4 hours after cleaning its own filesystem (I have aggressive cleaning enabled).
I've talked to PA and they are happy to walk me through cleaning up the disk space, as if I have nothing better to do than proactively manually clear my customers' disk space for all my customers with PA-220's every week.
