Hi,

Whenever a long url is received by nginx and php5-fpm, I get the following error

child 2989 said into stderr: "NOTICE: the log buffer is full (1024). The access log request has been truncated.

I know that most of these long urls are legitimate so I would like to receive them without having this notice.

Which means I probably need to increase buffer size.

Which directive is responsible for the buffer size?

thx

Hello,

I was facing same issue, here is what i investigated:

you can change php-fpm.conf access.format variable to something that will not exceed 1024 bytes(saddly there is nothing to limit size of particular variable like url which can solve this issue smartly).
Or you can recompile PHP-fpm and define MAX_LINE_LENGTH to something that fits your need.
or which i have choosed: change application to not use so long URL, which is IMO not good practise and balasts your logs....
