As of today, almost every time I do a git command, gc is getting
invoked.

  There are 96 pack files.

That's why. See gc.autopacklimit in "git help config" -- by default,
git will gc if there are more than 50 pack files.

Actually it looks like it is combination of this and packSizeLimit set
to 30M.  Git notices that it has too many packfiles, and tries to
repack them, but packlimit forces Git to split it into small
packfiles... and end up with more packfiles than limit anyway.

Thanks to everybody. This is exactly what was happening and the problems
went away when I set the packSizeLimit higher ... 3000M

 
Why did you set packSizeLimit at all?

Perhaps git should notice that it has nonsensical combination of
options...

That would be nice. It should be reasonably easy to work out that the
packSizeLimit will guarantee too many pack files after the gc.
Disobeying a users wishes shouldn't be undertaken lightly, but sometimes
we stuff up :) 

Well, git can simply notice that each except perhaps on file has
size greater or equal to gc.packSizeLimit, and then ignore gc.autopacklimit
hint, because repacking would not reduce number of packs, and not lower
it below gc.autopacklimit.

If `git gc` is called interactively, we can warn user about this situation...
