Untangle 7.2 and Memory Usage

[yuanyudistira]

Dear all

I notice that my untangle box is upgrade to 7.2
But there is a problem after upgrade.

Memory usage become very high (see attachment) 78% / 2793 MB (total 4000 MB)
2. Bad users experience. Browsing become very slow.

I really have to create by pass route in order to users complain.

Anyone can help with this situation?

If I restore untangle to previous backup file (UT 7.1), will this solve the problems?

1. Is there anyone experience the same problem after upgrade to 7.2?
2. does the 78% memory usage really cause slow internet browsing? or maybe something on 7.2?

Thanks

Yuan

Your memory usage is normal. Linux memory usage is higher than Windows usage, and people always make that comparison thinking that something is wrong. Your CPU load is very high...that's why things are slow. I also noticed that you upload nearly 4 times more than you download, though I don't know over what period of time that is. Make sure that you are running Attack Blocker and make sure that you don't have any spambots on your network.

Here i attach another screen shot of CPU usage.

At average, memory usage is around 50%

Attack blocker is on (see attachment)

TX = 34.95 KB/s
RX = 370.85 KB/s

Does it measn more download than upload?
I think this is quite normal ....

can you drop to the command line and run 'ps aux --sort rss'
and paste the output here?

memory usage shouldn't be that high so you probably have some issue.

I have another problems,...
It's been long time did not login to command line, i forget the password.

If I restore to factory default will it solve the problems?

Thanks

I also have a mem question, I've had UT running for over a month, everything appears to be working as it should, but i turned up snmp and know i'm receiving an snmp flag for high memory utilization "memory has insufficient capacity or is malfunctioning" when i looked deeper i found:

-UT console reports
physical memory 3449.59mb total, 1351mb used, 2098mb free
swap 2714mb swap, 255mb used

-top command reports
physical memory 3368736k total, ~ 3240000k used, ~ 125000k free, 25096k buffers
swap 2650684k total, 249424k used, 2401260k free, 1894172 cached

platform specs quadcore cpu 2.33ghz, 4gb ram, less than 500 users
attack blocker and spam filter not installed, all other apps are enabled
I know that linux memory utilization is different, but the UT app is reporting 40% memory used, and the OS says over 90% used, so the question, of course, is why the difference?

Ignore top it will only bring confusion - use 'free -m' and look at the second line

7.2 drastically changed my memory usage. I used to only have 400 megs free. Now I have 1300 megs free. I'm not sure if that is a good or a bad thing hah. But it seems MUCH more efficient now.

[proactivens]

I'd say thats a good thing then

No it does not. The factory reset restores the gui password. Few options, you can reimage it clean, or try the linux root password recovery.
