I am using UTM9 on a home network, using a low-end Dell desktop with 3GB RAM, Core2 Duo CPU. It has been working fine for many months, to protect our family's network.
Last night, I installed some overdue UTM9 updates and ever since, I've been having significant problems.
Update History: I had been on 9.407003 for several months. Last night, I applied the following updates:
9.409009
9.411003
9.412002
9.413004
After those updates, randomly (at least hourly) I have been getting the dreaded "[INFO-141] Http proxy not running - restarted" email. At this point, we can't pull up web pages.
This morning, I was offered another update, to 9.500009, so I went ahead and applied that, hoping it might help, but it did not. Throughout the day, today, at seemingly random times, we are not able to get to web pages, and I get the "[INFO-141] Http proxy not running - restarted" email.
Through some troubleshooting, I have found that the UTM9 is going into a high load situation, caused by excessive Disk i/o. Using atop, sorted by disk usage, I found:
PID TID RDDSK WRDSK WCANCL DSK CMD
1002 - 174.4M 0K 0K 100% httpproxy
3778 - 0K 432K 0K 0% postgres
3782 - 0K 176K 0K 0% postgres
3785 - 0K 112K 0K 0% postgres
2327 - 0K 28K 0K 0% jbd2/sda6-8
(snip)
As you can see, httpproxy is using 100% of disk... all "reads". Why? I have no idea. But, at this point, it all goes to heck and we lost the ability to browse the web, until it stops, and things start to recover.
I did a "smartctl -H /dev/sda" to check smart status on my hard drive, and it is clean. I am in the middle of doing a read-only bad block test (badblocks -sv /dev/sda) but doubt it is going to find anything.
I have turn off all logging, to see if that would help, but it did not (saw that idea in another thread).
Any other ideas out there? What other information can I provide?
