subrequest cycle cause cpu 100%

February 02, 2015 10:38PM
hello,

I use error_page = /500.html to show myself 500 page, and for some reason, I need ssi include in 500.html, for example:

500.html

<!--# include virtual="/fastcgi/global" -->
<!--# include virtual="/fastcgi/cap" -->
<!--# include virtual="/fastcgi/header" -->

if fastcgi upstream return 500 response code, it will cause subrequest cycle, a set number of error logs such as "subrequests cycle while processing "xxx" while sending response to client".

but if I add "wait" parameter in ssi

500.html

<!--# include virtual="/fastcgi/global" wait="yes" -->
<!--# include virtual="/fastcgi/cap" -->
<!--# include virtual="/fastcgi/header" -->

I find endless error log such as "subrequest cycle" in error_log, and cpu go up to 100%

I wonder why wait parameter cause so strange case, thanks


best regards
