If it helps, 'ps ux' command on linux shows about 600 '/work/Apache2/sbin/httpd -k start' processes (I set ServerLimit 40000, MaxClients 40000, for my prefork mpm) and the autobench output reads: httperf: failed to connect to SSL server (err=-1, reason=5) httperf --timeout=60 --client=0/1 --server=cage17.lan.ac.uk --port=8083 --uri=/secure/area/index.html --rate=30 --send-buffer=4096 --recv-buffer=16384 --ssl --ssl-no-reuse --num-conns=9000 --num-calls=1 Use of uninitialized value in numeric eq (==) at ./autobench line 184.
