You gave me a good idea for psutil: https://github.com/giampaolo/psutil/issues/1149 According to this cmdline tool: https://cr.yp.to/daemontools/softlimit.html ....the limit should kick in only when the system memory is full, whatever that means: <<-r n: Limit the resident set size to n bytes. This limit is not enforced unless physical memory is full.>> ...so that would explain why it had no effect. -- Giampaolo - http://grodola.blogspot.com
