profiling - How to debug a java heap OutOfMemory error in a production environment? -


our web app running in tomcat7 , we're using java 1.7.0_55....in past when we've had problems we've been able debug in our development environments using eclipse , profiler (the name escapes me @ moment).

now we're getting outofmemory exception in our production environment. i'm quite leery of running profiler in production environment question is...is there way debug problem in production environment without using profiler or there light-weight enough run in production?

just take heap dump of production server & analyse eclipse memory analysis tool. can copy heapdump local. eclipse memory analyzer best tool job. however, trying ui run remotely painful. launching eclipse , updating ui load on jvm busy analyzing 30g heap dump. fortunately, there script comes mat parse the heap dump , generate html reports without ever having launch eclipse!

check out.
