Crash & reboot, active process "pfpurge"
-
This morning pfSense crashed. It might have been triggered by an admin login via the WebGUI (I heard the beep which usually indicates a successful admin login, and a few seconds later the beep which emitted by the BIOS when the box boots up). The crash occured before the update to today's new firmware version.
The crash dump (which I dutifully submitted via the WebGUI) indicates that a process "pfpurge" was active at the time of the crash - not surfe how accurate this is, as I guess that on a two-core CPU more than one process might be active.
The crash was caused by some sort of page fault. Which I found a bit suprising - swapping is anabled on my installation, but I've never seen anything other than "0% swap usage". Heck, the machine has 2GB RAM and I've never seen memory usage outside 9-11%.
This was also the first time pfSense crashed for me. The hardware is an Intel D2500CC (http://downloadmirror.intel.com/20718/eng/D2500CC_TechProdSpec06.pdf), with a 4GB SATA SSD.

Either this has been fixed with the Wed Jul 3 15:44:12 EDT 2013 build, or it happens irregularily,
The crash report in http://forum.pfsense.org/index.php/topic,64130.0.html look similar, as far as I can tell.
However, I cannot currently reproduce this crash.

I could reproduce it while trying passive FTP with a browser:

Although sometimes pfSense just freezes. -
This morning pfSense crashed again (build Thu Jul 4 03:04:00 EDT 2013). This time, it appears that the browser re-used my session from yesterday evening (I have a very geneous session timeout set), so I accessed the WebGUI without login. No crash there, yet.
It crashed a few minutes later, when traffic rose to 100MBit/s. The crash report mention "pfPurge" again. However, I accidently submitted (and deleetd) the report via the WebGUI without saving it for me, so that's all I got for information.

If you can, you should try to use the older 20130701-1521 snapshot. I have not been able to crash that one yet…
