Set this options to JVM, and it will make heapdumps automatically.
Will these heap dumps be the same size as the current tomcat memory
utilization?
Yeap, and OOM
Just remember that the numbers out of top are at best approximations, and, as
Rainer pointed out, not taking measurements immediately after a GC is a
guarantee of an apples versus oranges comparison.
The appropriate tools (e.g., VisualVM) must be used for any rational analysis.

One correction, option -XX:-HeapDumpOnOutOfMemoryError disables heapdumps on

Hi Mark,
Sorry for the ambiguous 'unload' language, I suppose the tomcat language
would be 'context stop'. The issue occurs when deploying the WAR using the
Tomcat Manager interface (*not *by dropping the WAR in /webapps).
You should be able to reproduce the issue with these steps:

Hi Chris,
If MyClass had been loaded at initialization time (like your sample
code shows), it should not have needed to be loaded back off the disk
for shutdown.
In my first example, the ClassNotFoundError is thrown when enabled=false.
When enabled=true, the error doesn't occur.

Also interesting is cat /proc/PID/maps but here one would need to calculate
sizes per line from the two hex addresses given at the start of each line.

, $_;' | sort -n
