I ran into this with IPC::SharedCache a couple of months ago and had some
discussion with Sam about it. The problem is a lack of shared memory
segments and/or semaphores compiled into the kernel. IIRC, the default for
both under Linux is 128. The BSD system I was trying to use only had 32
segments and something like 10 semaphore identifiers. In order to scale
a system, you'll need to recompile the kernel with higher limits.
