503 Errors

[Matty]

I keep getting lots of 503 errors when i'm visting certain pages of my site.

I;ve been looking in the logs for the site and in the access log I can see:

86.14.148.173 - - [07/Apr/2016:00:08:00 +0100] "GET /pages/links.html HTTP/1.1" 503 665 "http://theuk.directory/" "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.110 Safari/537.36"

I don't have anything showing in the sites error log thou.

but if I look in the log kern.log file I've got

in my stderr.log file

its odd becuase i'm running multiple copies of the same software and its not doing it over other versions of the site 

oh and i'm running 1.4.15

This info seems due to the PHP crash which caused the error.
You may want to update the php and also you can update openlitespeed, the latest stable version is 1.4.16.
Thanks.
David
