made a simple testapp spawning a SSLeay connection thread on each
connect, works
stresstest:
telnet localhost 5432 </dev/zero >/dev/null &
and so several times.
about 30 at least, less than 60
memory was quite low then (64MB ram, 20MB swap). extensive swap started.
killed server. killed telnets ( linux was at its knees allready)
telnet screamed buffer overflows (me wasnt sending much data )
not much processes were left, usually I have 40 MB free+buff+swap with
that much of processes. None of them consumed much memory.
about 30MB was gone. No sign in /proc/* files or kernel status dumps
I did not allocate any significant amount of memory in threads, so , most
of it should have been gone to where ?
