Re: [SLUG] Too many open files

Look in $kernel_source/include/limits.h.

Change NR_OPEN to whatever you like -- like 16384 and recompile. It comes
out-of-the-box with 1024.

If glibc still gives you crap, recompile that against the new kernel sources
after you make the change. I don't think gcc will bomb after this. It's a
compiled in limit.

If this blows up for any reason, it's not my fault.
