Try disabling the use of memorybased filesystems.
My /usr/local/etc/synth/synth.ini sports:
Maybe you should limit the number of builders (workers) and the number
of jobs each builder can run simultaneously.
On a dedicated 8 core builder at $WORK, I use 4 builders with 4 jobs
each, thus placing a high strain on the CPUs in the worst cases.
You should also give synth roughly 1.5 - 2 GiBs of memory for each job
run in parallel.
On my own 4 core server, I use 2 builders with 2 jobs each.
