Hi,

I've got half a dozen RV042 routers in various locations.  They are running v4.0.0.07.  Seemingly randomly, I got the

502 Bad Gateway

The CGI was not CGI/1.1 compliant.

error when attempting to log into the web interface with google chrome (same with IE too).  This happens from the LAN side.  I actually didn't notice it until my Opsview monitoring software threw up a critical when it didn't get an http response. 

The router is otherwise actually working just fine.

Since the first occurance, more of my routers have developed the same error.

I've tried different browsers, clearing caches, though I'm not surprised those efforts were fruitless, as there is clearly a problem even when no browser is involved (nagios).  The nagios http check also returns a 502 Bad Gateway.

I suppose a reboot is in order, but I'm looking for other explanations/solutions before having to reboot, as I'd like to avoid that if at all possible.  If I can provide any more input, please let me know.

Thanks for the help.
