Can you provide more context? :help mentions that 'previewheight' is
just the default value. If there's an existing preview window, it
will be reüsed, and its height won't be altered.
[...]
Perhaps Eclimd sets up some autocmds that explicitly set the window
height?
The preview windows height in the example you gave are also 4 lines.
(When I disable the work-around of course...).

I've encountered this issue when I've used the fugitive plugin (a
plugin for git).
The plugin adds the command :Gstatus that opens a preview window.
The thing is that in my vim that preview window height was only 4
lines, even after I've explicitly set previewheight=50 in my .vimrc .
So each time I had to resize it by hand (Ctrl-w 20+)
I installed that plugin and had no problems with it respecting
'previewheight'.
I still think it's either:
1) something else setting previewheight:
Try, after opening a preview window that is unintentionally 4 lines
tall:
:verbose set previewheight?
or
2) something with an autocmd, but I don't really want to dig through
your .vimrc and .vim/ dirs.
If you have a lot of autocmds, you might want to :redir them to a file:
redir! > autocmds
silent! au
redir END
new +/\\cpreview\\\|pv autocmds
So to workaround this (annoying unproductive) problem - I did what
I've posted to SO (I am theosp) .
Using a BufEnter autocmd seems sensible.
Why the ?* in this line? just ensuring it's a named buffer?
au BufEnter ?* call PreviewHeightWorkAround()
And a shorter version (a function seems like overkill):
au BufEnter ?* if &pvw | let &l:wh=&pvh | endif
see:
:help :let-&
