    Default Weird problem

    I'm sitting here, and all of a sudden Pidgin goes out, and then the browsing dies. I try to log into Untangle, and it says the webservice is unavailable.

    The hard drive light is blinking over there pretty heavy, and I can hear it churning.

    A few minutes later, or less, everything is working, and all the apps have reset numbers on them, like I just rebooted or removed an app.

    It's done this twice in 10 minutes now.

    Where should I look for problems?

    Haven't had problems out of this thing since I installed it 4 months ago, but I did add the ad blocker a few days ago.

    Take a look and see if you might be getting upgraded to 6.2, they are currently pushing that out through a phased approach.

    Checked system info.

    Summary:
    UID: 6d5c-ef91-18f6-5902
    Build: 6.2.0~svn20090527r23446release6.2-1lenny

    Java: 1.6.0_12

    Now, my updates are scheduled for a 11pm install...wth?

    Now, I installed Ad Blocker two days ago...this was a 6.2 item, right? So I should have already been at 6.2 before today's issues occurred...

    I believe that is correct, I currently do not have 6.2 so I can not speak of when Ad Blocker goes in. During your inactive sessions what is happening with CPU/RAM? Can you drop to the terminal and see if anything else is working/having problems?

    what are your system specs? could be low memory and swapping.

    you can check that easily by running 'top' and watching the load
    or 'vmstat 5' and watching the swap in and swap out numbers.

    I have 1.5 gigs of ram, on an AMD 3200, 2ghz, I think. Ali chipset with two realteks. Socket 754 chip. I've pushed it pretty hard, have 20/5 FIOS here, don't have issues maxing it out over many hours of Bittorrent or other downloads.

    It said 100% CPU usage when it froze. The second and third time it became unresponsive, there was no HD activity, and it came back quicker. Each time, it reset the counters on the display of the rack apps. GUI says it was using 1100Mb of ram, with 400 free. It's been using more ram lately, up until a few weeks ago, it was only using 700mb for about 3 months or so.

    I haven't dropped to the command line yet, or had to ssh into it, and I don't have direct access to the command line until I hook up this monitor. So, in short, I don't know any command on the shell for this. Not really a linux guy, but I do follow instructions fairly well. ;-) So be verbose is you want me to use the command line, I'm a serious noob in that regard.

    The weird thing about all this, is that traffic was pretty idle when this happened. It's not like I was downloading anything...I was reading a blog, with nothing going on in the background. I was the only one home, and the laptops were off. The Gui did say the recieving was at 100k the first time it locked up, even though my firewall said .5b/s.

    The first time, Pidgin dropped really hard, the subsequent times, Pidgin never disconnected, but the web went down.

    The web Gui for Untangle was unresponsive every time the web went out. Only hit the swap file once, the first time, when Pidgin died. It hasn't reported using more than 1100mb of RAM and change.

    Default You're not alone

    This just started happening to me as well. I have maybe, 20-25 users behind Untangle on a P4 2.0 GHz w/ 1 GB RAM. Everything used to be fine. No problems whatsoever. Now users are complaining that internet pages are often coming up as unavailable due to page load timeout.

    When I try to log in to the admin page, I frequently get a timeout error that can last anywhere from a few seconds to a few minutes. Pings, which normally complete in < 1ms, take 2-8 ms. If I am logged in to the admin page and have SSH-ed into the box via Putty at the same time, I frequently get disconnected from both at the same time. The admin page says, "The Session has expired. You will be redirected to the start page." But this happens while I am actively using Untangle. Putty tells me, "Network error: Software caused connection abort." While access is unavailable and I try to reconnect, Putty tells me, "Network error: Connection refused."

    System Info is as follows:
    Summary:
    UID: aa96-0ed2-d11a-5502
    Build: 6.2.0~svn20090527r23446release6.2-1lenny

    Java: 1.6.0_12
    There are no torrent clients. My IP is not showing up in the Attack Blocker logs. Neither is anyone else's for that matter. Something appears to be going terribly wrong internally, but I don't know where to begin to look. Lucidtek, I feel your pain

    Is it possible that it is rebooting due to the CPU overheating? Bad fan maybe?

    Default Not rebooting

    In my case, anyway, the box isn't rebooting. It's just not accepting any traffic except ICMP pings for anywhere from a second to a few minutes.

    I don't know if this is revealing or not, but I have disabled the Attack Blocker and the problem persists. While I was unable to connect, I pinged the Untangle Box.

    When the box was unresponsive, the ping times were almost all > 1ms and the TTL was 255. Once it started responding again, all pings are < 1ms and TTL=64.
