The RV042 502 Bad Gateway CGI was not CGI/1.1 compatible

Hello

I have half a dozen routers RV042 in various places.  They are running v4.0.0.07.  Apparently at random, I had the

502 bad Gateway

The CGI/1.1 CGI was not consistent.

error when you try to connect to the web interface with google chrome (even with IE too).  This is happening on the side LAN.  I actually didn't notice until my software Opsview monitoring threw up a critical when he did get an http response.

The router otherwise actually works very well.

Since the first occurrence, several of my routers have developed the same error.

I have tried different browsers, clear caches, although I'm not surprised that these efforts were in vain, because clearly there is a problem even when no browser is involved (nagios).  Nagios http checking also returns a 502 Bad Gateway.

I guess that a reboot is in order, but I'm looking for other explanations/solutions before having to restart because I would like to avoid that if possible.  If I can help more, please let me know.

Thanks for the help.

I know you are trying to avoid a reboot, but I would try and see if the problem goes away.  The rv series starts acting funky when they have not been restarted for awhile.

  • Cannot add the vmkernel nic: a specified parameter was not correct. vSphere CLI + ESXi 4

    Hello. I try to add vmknic with frames in my distributed virtual switch.

    I read the vSphere command-line Interface Installation and reference Guideguide:

    "vicfg-vmknic - a-i DHCP"vmk5"

    I see the error message:

    Cannot add the vmkernel nic: a specified parameter was not correct.

    Vim.Host.VirtualNic.Specification.Ip

    What's wrong?

    I tried all the combinations of parameters with the same result.

    Ok! I've found a workaround.

    Since adding a vmkernel remote interface doesn't seem to work with DVS, I simply created one on a standard vSwitch and it then migrated to the DVS. And voila: the value 9000 MTU migrated intact with her! Here are the steps I followed:

    1. put the ESX host into maintenance mode - evacuate VMs manually if necessary

    2 remove the VMKernel iSCSI/NFS to the DVS interface

    3. create a standard virtual switch with no physical cards. He has no need to be a VMKernel VM Networking switch is fine. Make a note of the name you gave to the PortGroup created on the new vSwitch.

    4 using the remote control line, add the new interface vkernel specifying an appropriate jumbo MTU (9000) and the PortGroup on the standard new vSwitch. For example:

    esxcfg - vmknic.pl - Server

    If you get 3 answers, everything works. If you get failures, something has gone wrong. Go back and check that the interface is configured correctly using the command list esxcfg - vmknic.pl-.

    Enjoy!

    Andrew,

    RE: 1 - because now I just want to be able to see step by step what happens when rendering or submit occurred.

    Running in debug mode will show you that.

    RE: 2 - you said: "then the method I described (that you used) is the simplest way." I'm not sure I understand - what methodology?

    You said in the second post on this topic, "the approach I used to nail the region is the link: here", and you have access to a post where I described how I would do, still shows here:

    I would disable systematically on the side 'show' of the page. Start by regions. Put a condition never on each. Run the page. If the error Stops, you know that the problem was in one of the regions. If this is not the case, turn off the process and calculations, etc.. Then enable these components one by one until the problem recurs. When you conclude that the problem area (if it's a region), then disable the elements and buttons in the region and so on. The problem may be due to an unhandled exception somewhere inside one of the components.

    RE: 3 - all types. It is not clear (to me at least) if the binding occurs correctly, what values are passed to the pl/sql. I have referred to the session variable correctly or I made a typeoff, etc., etc.

    Again, more details on the situation would be useful. At page debug output is not sufficient, and equip your own code is not enough, you can always find your database session and see what happened. Add & ptrace = YES to the URL, run the page or send the page check the destination database for the trace file and tkprof dump to get a report.
