Hi everyone,
i'm trying to upgrade an nginx-binary while running.
When i do kill -s USR2 <pid>, i get the following error in the logs..

11:40:38 [alert] 52701#0: execve() failed while executing new binary
process "/opt/sbin/nginx" (7: Argument list too long)

Anybody knows what exactly is in those arguments ? We have ~ 20-55 worker
processes if that might be related..
nginx-version is 1.18.0, os: debian buster

thanks everyone in advance!
