I'm running a (self-signed) SSL cert site on Apache/2.2.14 on Ubuntu 10.04, but various browsers are giving errors on half the connection attempts. Just now saw this transient error from Chrome:

"Error 126 (net::ERR_SSL_BAD_RECORD_MAC_ALERT): Unknown error."

Hit refresh and the problem goes away for a while.

wget too:

$ wget --no-check-certificate https://dev.partyondata.com/deps/
--2010-09-08 19:30:26--  https://dev.partyondata.com/deps/
Resolving dev.partyondata.com... 184.72.53.220

Run it right away again and it works:

$ wget --no-check-certificate https://dev.partyondata.com/deps/

In my sites-enabled/default-ssl:

SSLCertificateFile    /etc/ssl/certs/ssl-cert-snakeoil.pem
SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key

The cert:

-----BEGIN CERTIFICATE-----

-----END CERTIFICATE-----

The cert is in turn generated via:

$ make-ssl-cert generate-default-snakeoil --force-overwrite

Apache version.
