Try disabling the use of memorybased filesystems. My /usr/local/etc/synth/synth.ini sports: Tmpfs_workdir= false Tmpfs_localbase= false 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. -- Trond.
