Yo, I'm debating a small patch for 1.4.2 that would add (more) commandline warnings for memcached. You'd of course only see most of them if you fire it up without the -d option, but hopefully in the course of testing someone tries that.
For exampple, if someone sets `-m 12` they'd get a warning saying the amount of memory is too small, and they're likely to get out of memory errors. And if they set `-t 50` it would warn that having threads > num_cpus is wasteful. I think a few of our frequent issues can be solved by having memcached audibly warn when configured weird. I also want to add more twiddles that can be used for foot-shooting. Thoughts? I'll do up the patch tomorrow anyway but want to see if there's any discussion to this. -Dormando
