"Server too busy" after moving to fcgid

Question

I was previously using mod_fastcgi and had issues as described here with configurations getting ignored. After moving to mod_fcgid, I've seen a whole new issue which is causing issues for all sites hosted on the server.

At random intervals throughout the day, the server outputs a "Server too busy" message to requests and I'm not sure what is outputting it- fcgid, apache2 or varnish. Under what circumstances would this message usually show and what are my options to prevent it from happening again?

Thanks

What does the _rest_ of the message say? – Michael Hampton Mar 03 '14 at 16:29 — Michael Hampton, Mar 03 '14 at 16:29
That's literately it, with a 503 code! – MrNorm Mar 04 '14 at 10:29 — MrNorm, Mar 04 '14 at 10:29
Didn't you check the error log? – Michael Hampton Mar 04 '14 at 10:31 — Michael Hampton, Mar 04 '14 at 10:31

Checking out varnish and apache2 showed that they both returned 200 OK codes. The issue was actually load balancer on our hosting providers network intercepting responses.

Give Apache a bigger RAM allowance! Apache 2.2 defaults to a very small amount so you would probably want to increase it (Unless you have a terrible PC)!
