Please, administrators like tunables and knobs for changing default values.
Not only for being empowered to fix things themselves but also to be
able to dig into a problem and find the root cause...
I remember that i had more then one occasion , where i grepped for
timeout or other limiting values in proxmox or other softwares source,
and often gave up in the end, because it was too deeply hidden or i got
too many hits/findings.
Finding such without knowing the code can often be like searching for
the needle in a haystack and extremely frustrating.
I would be happy, if such important values would get defined with some
descriptive variable name at a suitable location, maybe even with some
comment what's it all about ( even if it's not meant to be changed/tuned)
just my 10 cents...
