Subject: [nio-devel] nio-httpd error
Message-ID: <87u0792msu.fsf@agni4.cltp.com>

Hey,

I was testing the nio-httpd server with ab2.  With concurrency level
set to 1 I can serve up to 930 pages/sec.  But as soon as I change the
concurrency level to anything above one I get the following error. But
this is at the end of the benchmark run.  For example : I ran ab2 for
1000 requests to the 'dyn' page at concurrency 5.  It completes the
benchmark with 1000 requests completed (7 failed) and I get the
following error in the REPL.

thanks,
