My wild guess is that SHA1::Upgrade() function is being called each time mod_ssl sends a packet to the peer. Asuming that you never have the same network conditions (tcp/ip slow start, packet loss => the size of packets might differ and some packets can even be sent few times) hence the number of invidual packets is difference, hence the number of upgrade calls is different. I am not sure if that is the reason, but i am not able to figure out anything else than that. -- Regards Grzegorz Rusin ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager [EMAIL PROTECTED]
