503 errors

[Dani]

Hi,

I've lately been flooded with 503 - graceful restarts. which hasn't been there before. We haven't upgraded that much so I cannot pinpoint the errors, is there a way for LS to log these errors somehow?

Do you have access logging enabled? you need to find out which script causes the 503 error. You can turn off "503 auto fix".

[Dani]

no i dont but if the 503 would appear there I'd have no problem turning it on for a short while. What's the worst thing that can happen having the auto fix off?

[Dani]

ok I found that 2-3 url:s are causing the 503

[30/Sep/2007:21:40:49 +0200] "GET /profile/check_new_stuff HTTP/1.1" 503 401 "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)"
[30/Sep/2007:21:40:49 +0200] "GET /get_ad HTTP/1.1" 503 401 "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; FunWebProducts; SIMBAR Enabled; S


but all these "scripts" return is a text like "a:b:c" where a||b||c == 1-100

This is a header from the check_new_stuff url "when it's working"

Does this say it gzipped it? Even thought my gzip is set to 300?
Maybe it has something to do with the short length? /get_ad returns 45-60bytes text.

thanks




**edit

I just realized that since this is a php file the output will surely not look what size the output is since the settings only touch the static files

"Min Static File Size (bytes)"

Any chance for a dynamic one?

[mistwang]

The response was gzipped. It is hard to apply the limit for dyanmic request as somtimes the real body size is unknown when the web server need to send back the response header.

[Dani]

so you also think the file is to small perhaps? maybe I can fill it with some junk just to get around the 503 errors? =)
