I have a java process running on unix/solaris 2.8 taking up a lot memory. Memory mapping command(pmap -x ) for this java process lists a lot of Mapped files as [anon]. Does the anaonymouse block mean memory leakage in the process? The above mentioned java process's memory requirement seems to be growing with time. Is there any good tool to analyse the memory usage/leak ? output of pmap -x command 7624E000 1424 1016 48 968 read/write/exec libvtlocale3_o3gri.so 763B2000 16 - - - read/write/exec libvtlocale3_o3gri.so 763C2000 8 8 - 8 read/write/exec [ anon ] 763EE000 16 16 - 16   More>>

I'm not sure about pmap - I haven't used it before, but jProbe or OptimizeIt probably have the functionality that you require.
