Comment(by kdajka):

 @kb Could you enlighten me how to calculate stack space? I reduced
 thread_pool_stack to 256KB with
 varnish_edd0d11803810d30566c883a9b6d1fcbdc12b69f, without any success

 I think that there could be problem in memory allocation in trunk. While
 using 2.1.5 with -s malloc,9G I'm having 174799 objects, with trunk -s
 malloc,1G I had 315918.

 Here is varnishstats for another instance running varnish 2.1.5
