@claudiu_beta as you are using packages from my repository, can you please test "7.3.6-2"
from "remi-test" which includes the new proposal fix from @bukka ?

@bukka sorry for the delay... quite busy these days.

(P.S. build available for F29, F30 and EL7)

I just pushed another attempt to fix this to the PR. I also pinged Remi if he could kindly create
another RPM to test.

Ok thanks again for testing! Indeed it will result in quite a few new open file descriptor -
basically one for each child in the master process which might be quite a lot if you are using
around 1000 pools which means even more children. So this is not probably good idea either.

So it seems like the markers in the output are the only possible solution for flushing. I think
there are some issues in the logic atm. - the whole read loop is a bit messy so I will try to
improve it and see if it addresses the issue. The thing that it definitely goes through that logic
as the message is still decorated by zlog...

With this patch, now I have other bug and sites are completely down until php-fpm restart. A lot of
lines like these. I never had this before. I have ~1000 pools using php7.3.

I have installed "7.3.5-2" from Remi, but I need few days to test it, to be sure the
result is accurate.
