Description:
------------
Since few years (around 2 years now) on different versions of php-fpm sudden unexpected time outs are being observed. The php-fpm software refuses to accept any connections. Manual restart resolves the situation until same behavior appears again after some random time. 

No specific pattern causing such behavior has been observed so far. It may happen on production server with hundreds of pages served as well as on totally fresh server with 128GB of RAM not serving anything.  Tested both with nginx and directly trough the socket.

Does it reassemble any issue that you met so far or was reported by anyone? If no, do you need any further information or there is any form of debuging that you would advise in this case?

Hello,

I have exactly the same problem with fpm. My config:
FreeBSD 11.2-RELEASE-p1
php56-5.6.37
php70-7.0.31
php71-7.1.20
php72-7.2.8

PHP built from ports.

log_level = debug -- logs look the same as when everything works fine.

I thought maybe the problem is kqueue (events.mechanism).
My pools use pm = ondemand

Can any developer look at this problem?
