I would imagine that to be because Linux by default only allows 1024 file
handles to be open at once. If each of the qmail-remotes has a message in
the queue open, then having too many can cause "bad things", as we found
when we needed to run a few hundred extra virtual domains on our web server,
and the same thing happened.
Despite the docs at RedHat.com, saying how easy it is to increase the
file-handle limit on the new kernels, I found that it simply didn't work.
Editing the source and recompiling the kernel (as you had to in older
kernels) did the trick.
It's not even that hard, that was the first time I had ever fiddled with
the Kernel source. We went to 4096, which should allow for quite a few
qmail-remotes. : )
