I had SqWebMail 3.6.2 up and running on a new server, yesterday.
Then I moved a busy mostly-CGI site to the new server -- and now SqWebMail won't go. It reports (consistently):
"The webmail system is temporarily unavailable. An error occured in function CGI: CGI environment exceeds allowed maximum size."
Uh, whose "maximum size"? Is this a system variable I don't know about, or a new Apache 2.0 config setting-related maximum, or...?
Well, I seriously doubt I have your answer, Jeff... But I can almost guarantee you that if it's a system related problem, someone here who *might* actually know the answer wouldn't be able to tell you for sure -- unless you let us know what system you are switching _to_ to begin with =) ... and possibly the "from" would be helpful as well, though not as likely so.
Also, knowing whether any other CGI's are reporting the same thing (such as the ones in the "busy mostly-CGI site" in particular) might be very useful indeed.
But if you want some quick guesses, then yes... I'd look for more information in the exact places you suggested.
Read up on your new system's constraints on environment variable count/size, in case there's a limit that's tripping you up. (Seems quite a bit unlikely, since SqWebMail really doesn't use all that much environment information, AFAIK. And "heavenly days!" if you're somehow using up all your environment variable limits on *any* platform by running SqWebMail I'd actually be quite surprised. -- But you should check it nonetheless.)
Read up on Apache 2.0 (you really should have done this anyway if you haven't, as there are significant changes from what little I know) and see if it has a default limit on the number of CGI processes launched, or memory used by child processes, or this, or that, or the other thing... yada-yada.
Btw, I presume if you disable the "busy mostly-CGI site" (you've tried that, right?), that sqwebmail then works again? -- If not, does it still give the exact same error? ... blah, blah, blah, I could keep talking forever, but I'm not gonna.
Check out some of that and get back to us, if you still need to, with other questions and/or more details.
