SSL_write errors

Hello Igor

We (Yahoo) are running a customized version of NGINX (based off 0.5.30),
and one of our customers is repeatedly getting such errors in his

2008/09/15 04:02:19 [info] 4822#0: *5983421 peer closed connection in
SSL handshake while sending client greeting line, client:,
2008/09/15 04:02:22 [info] 4822#0: *5982475 proxied session done,
client:, server:, login: “[email protected]”,
2008/09/15 04:02:22 [info] 4822#0: *5982475 SSL_write() failed (SSL:)
(32: Broken pipe) while proxying, client:, server:, login: “[email protected]”, upstream:

The SSL related configuration from nginx.conf is:

ssl_prefer_server_ciphers on;
ssl_ciphers ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;

Clients report frequent disconnects from NGINX proxy, and the upstream
server logs show that NGINX closed the connection to upstream.

Any help in this matter would be greatly appreciated.

Thank you
