Hi, I'm using stunnel 4.22 with OpenSSL 0.9.7m - I am using 4.22 because of the xforwarded-for patch and 4.27 is not supported.

I am running stunnel in standalone mode on a P4 3.2Ghz with 1Gb of Ram. When I start haproxy & stunnel after a reboot, free memory starts at about 750Mb then slowly degrades to about 45Mb. After 8 more hours or so of operation our site was completely unbrowsable. I checked our firewall for unusual traffic, and there were none.

Running top does not indicate any processes which are consuming all that memory and that is what I find weid. Only a reboot frees up the memory. Should I be running stunnel on more Ram?
