I have seen eclipse consuming lot of memory. At times it is even more than 1.5 Gig.

I have set up Java parameters in eclipse.ini as:

-XX:MaxPermSize=256m
-XX:MaxMetaspaceSize=256m

-Xms256m
-Xmx1024m

Any clues if there is any other parameter which I can use to cap it to about 1 Gig (or less)

Your question doesn't really make sense. There is no way to force less memory to be used than is actually needed, and you've said nothing about what you're actually doing. The best you can hope accomplish is to have the Eclipse IDE die/terminate because no more objects can be allocated in the heap limit you've set, and that seems far less than helpful. Some of the applications I work with require heap sizes of 5g or more simply because the data being manipulated needs that much space....

Typically have work on Java projects.

- eGit client to sync code
- Occasionally use eclipse debugger to debug / step thro' the code.

I usually memory usage increasing when remote debugging, HOWEVER it does not release the memory back when I stop debugging ..etc ..

If there is a reproducible memory leak, you'll need to open a Bugzilla report with a precise description of how to reproduce the problem. No JVM option will fix such a problem.
