Lacking further clues I did the trial and error thing and removed some

my Apache is working again. Thanks for the hint that the number of known
dlls could be a problem. I'd still appreciate more precise information
of how rebase works and if there is a more systematic approach.
The command rebase -is gives a list of the DLLs, their sizes and where
they are based.
The DLL size is in "field 5" as 'sort' recons fields, so
rebase -is | sort -k5 will dump the DLLs in size order.
Thank you. So if I take the first and last line of rebase's default output
the difference in the 3rd field tells me how much space is required,
correct? In my cleaned up installation it is 879.5 MB. Is it possible to
give a limit up to which this number may grow? Exactly what memory/address
space is being reserved here?
On my system the last DLL in the output is an LLVM DLL which I believe
is used by the X server. A lot of the top DLLs appear to be related to
the X server, some of those are code-generation DLLs for the LLVM JIT
to use. The footprint of the X server seems large.
In my installation LLVM takes up a lot (and for some reason I have three
different versions installed - have to get rid of some) but the biggest
