Comment(by octplane):

 Hi,

 We had the same issue and also moved the value to 1000 in hope this will
 fix the issue. I'd have hoped that varnish would try and nuke objects
 until it has enough storage.

 PS: we use a quite small cache size (20G) because we don't want to hit the
 disk and store small objects along with very larges ones, hence the
 problem...

 Cheers,
 Pierre.
