Comment (by des):

 Your varnishhist(1) output shows that most hits are processed in 10 to 100
 µs and misses in 1 to 100 ms, and the hitrate looks good.

 If I read your varnishstat(1) output correctly, your server delivers
 around 4 MB of data per second, plus protocol overhead, which is quite a
 lot (~40-50 Mbps sustained).  I would recommend switching to a 64-bit CPU
 (and OS) to get around the address space limitation.  If that really isn't
 an option, you can cap the number of worker threads with -w (e.g.
 -w20,200) to silence the error messages.
