You can get some manner of memory pressure relief by using the G1GC (which
lets the OS reclaim memory) and forcing GC's once in a while.
Leiningen has 2 JVMs.
In my ~/.emacs.d/init.el:
(setenv "LEIN_JVM_OPTS" "-XX:+UseG1GC") will catch the leiningen JVM.
In my ~/.lein/profiles.clj
:jvm-opts ["-XX:+UseG1GC"] will catch project JVMs.
You can force a GC on all java processes with some variation of:
ps axf | grep java | grep -v grep | awk '{print "jmap -histo:live " $1}' |
sh
This will help keep the footprint low at steady-state.
