Package: php5-fpm
Version: 5.4.45-0+deb7u1 Konsole output


php5-fpm reload fails if there are too many pools defined. There is no
upper limit on pool number, but if the daemon receives a SIGUSR2, the
current socket names are written into environment variable (to
re-acquire later), then execve() is called. With all the unix domain
sockets' paths in the env, execve fails with E2BIG, and php5-fpm exits.

I have tried to raise max stack size, as according to man 2 execve, max
env size is  min(0.25*RLIMIT_STACK, 32 page), but the problem remains,
as upper limit for one env string is 32 pages.

In our system, we tried to use fpm with 6k on-demand pools (most of our
websites are "should exist but no one will ever open it").

PHP should consider sending only FD numbers. If 4/8 bytes are used
instead of paths and IPs, 16k/33k FDs would be the limit (assuming 4k
pagesize), which wouldn't depend on path lengths; socket types and infos
could be acquired after execve. (And we could document it as a
limitation)  Alternatively, before execve, php5-fpm could write this
information into a tempfile, pass the tempfile's path as command line
argument with the execve,  then use that file after reload.

The bug is found in Wheezy, but Jessie should be affected, too.
