Probably a resource exhaustion problem, especially when you are talking
about "lots of wget processes".  Look in /proc/user_beancounters in the
container and see if you have anything that is non-zero in the "failcnt"
column like tcpsndbuf, tcpsndbuf, or numtcpsock.  Typically, I've found
the defaults for those resources to be particularly anemic, especially
when you've got a lot of network activity as in this case.  Any resource
with any non-zero failcnt should be increased in size significantly
(multiply by 8 or more) using vzctl set {veid} [resource=...] --save.
