Would help to know, at minimum: - ammount of ram - ammount of cpu's - platform (uname -m ) - pciconf -lv|grep ^none - dmesg output that complains about hardware - what's different about your kernel with respect to GENERIC What the problems are: - from the sysctl variables, I'm guessing you want more network performance - you mention core dumps, does the kernel crash? Some background: - what's the primary purpose of the machine - why are things like ipc tuned? > kern.maxfilesperproc=65536 The above will only work with programs that use open(2) exclusively and not fopen, because fopen is limited to SHRT_MAX, being 32767. -- Mel Problem with today's modular software: they start with the modules and never get to the software part.
