SSL_write errors

[Mansoor Peerbhoy]

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 nginx.log 

2008/09/15 04:02:19 [info] 4822#0: *5983421 peer closed connection in SSL handshake while sending client greeting line, client: 192.168.8.3, server: 0.0.0.0:993 
2008/09/15 04:02:22 [info] 4822#0: *5982475 proxied session done, client: 65.96.130.215, server: 0.0.0.0:993, login: "fred at domain.com", upstream: 192.168.8.40:143 
2008/09/15 04:02:22 [info] 4822#0: *5982475 SSL_write() failed (SSL:) (32: Broken pipe) while proxying, client: 65.96.130.215, server: 0.0.0.0:993, login: "fred at domain.com", upstream: 192.168.8.40:143 

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
