@Seldaek I think this may be a good path forward regarding the broken pipe errors people are seeing (including us, as well - as of 2 months ago). Do you foresee any issues with the stream being closed at the end of each write?
from monolog.
We have this issue as well in production, seems like file descriptors aren't getting closed as the issue appears more and more as the server uptime increase. Restarting the kube pod fix the issue for a while. So yeah there must be some missing fclose somewhere.
More information: PHP 8.2, Laravel 10, Monolog 3.5
Using StreamHandler into stderr, for Datadog
Really started to notice random 500 errors caused by this on our app after upgrading to PHP 8.2 and Monolog 3
Edit: we are using php-fpm
from monolog.
Monolog handlers have a concept of closing them. The StreamHandler will close the stream only when closing the handler (assuming you configured it in a way where the handler is the one opening the stream, not when passing it a stream managed externally that it could not re-open later).
Opening and closing the stream for each log message being written would quickly turn your logger as a performance bottleneck.

Yeah, as far as I understand it should closes on destruct
. There is most likely a leak somewhere though, can the destruct call get skipped for some reasons? (crash, long running processes, etc)
from monolog.
I think maybe what we could try here is to close the stream when reset()
is called, as that should be called between jobs in long running processes. That should ensure we don't keep a resource open for too long, assuming Laravel resets monolog correctly when needed.
