Java Memory leak detection

run GC and dump only reacheable objects

sudo -u tomcat jmap -dump:live,file=heapdump_live.hprof

don’t run GC and dump everything

sudo -u tomcat jmap -dump:format=b,file=heapdump_all.hprof

if nothing is fond or dump size is significantly smaller than memory amount consumed by app, restart app with this flag
