Can you give details about your setup and create a bug-report for
that? (one for the loss of code-completion and another for the memory
usage)

Please add the following data on the memory report:
1. are those eggs all with .zips or uncompressed?
2. How much memory are you passing to -Xmx ?
3. The problem is on requesting a completion or on a rebuild?

Note that java has the habit of going to the maximum and recycling
memory after that, so, if you pass 1GB to it, it may use all that even
if it could cycle before, as it usually goes for performance rather
than memory -- and it depends a lot on where you're seeing that memory
usage -- personally, I leave it around 500 MB (and I do work with some
large projects). It may be that it has some problem specific to your
setup, but I need more details to get into that).

Also, if you were able to pass a heap dump of your memory in the case
where you see it using too much memory that would help a lot (see the
Getting Started of http://www.eclipse.org/mat/ for details on how to
get that) -- just don't forget to zip it before sending (although it
can still be a big file, so, if you may need to put it in a ftp
somewhere so that I can get it). And also, it would be nice if you can
get a clean eclipse only with pydev to this test (as having svn or
other plugins will probably add too much noise -- in which case I
might not be able to get a proper analysis of the dump).

Cheers,
