Notes in php-fpm logs?

Question

linux

I noticed recently in the php-fpm logs the following notice:

[21-May-2012 21:12:51] NOTICE: [pool sitealias] child 15483 exited with code 0 after 15316.518 seconds from start<br>
[21-May-2012 21:12:51] NOTICE: [pool sitealias] child 18510 started<br>
[21-May-2012 22:24:52] NOTICE: [pool sitealias] child 15398 exited with code 0 after 19986.712 seconds from start<br>
[21-May-2012 22:24:52] NOTICE: [pool sitealias] child 19091 started<br>

I did not find similar problems on the network - usually everyone has this accompanied by some kind of errors, but after I started php-fpm'a - only similar remarks.

php-fpm -v<br>
PHP 5.3.13-1~dotdeb.0 (fpm-fcgi)<br>

Has anyone experienced something similar? Perhaps he knows how to treat?

Answer 1

In your settings, you have to restart the workers after a certain time or number of requests. So it's all right

Answer 2

It seems that in this way records are recorded in the log about restarting php-fpm processes, several of them hang and they are restarted by timeout.
They are marked as notice because php-fpm.conf defaults to:
; log level
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
;log_level = notice
