Martin - the value written to /sys/kernel/debug/tracing/buffer_size_kb is the amount of _contiguous_ RAM allocated for each CPU. The initial value of 128000 was somewhat arbitrary, so I decided to proceed likewise and arbitrarily divide the value by the number of CPUs. I've tried it on an Emerald class server (64 CPU) without any complaints in dmesg. It appears to have solved the issue on low RAM systems as indicated above.
