[Bug 254333] [tcp] sysctl net.inet.tcp.hostcache.list hangs

--- Comment #6 from Richard Scheffenegger <rscheff at freebsd.org> ---
Also, as a quick workaround:

What is the output of sysctl net.inet.tcp.hostcache

and the above problem about the waiting for a contingeous chunk of kernel
memory could be reduced, by restricting net.inet.tcp.hostcache.cachelimit
(the output tries to allocate (net.inet.tcp.hostcache.count+1)*128 bytes. With
a full hostcache this is almost a 2 MB memory chunk (on my system, the limit is
15360).
