Running OpenSSL 1.0.2h, and stunnel 5.32 I often get:

ssl_start: s_poll_wait: TIMEOUTbusy exceeded: sending reset 2016.05.17 16:51:46 LOG5[21]: Connection reset: 0 byte(s) sent to SSL, 0 byte(s) sent to socket 2016.05.17 16:51:46 LOG7[21]: Local descriptor (FD=15) closed 2016.05.17 16:51:46 LOG7[21]: Service [ssmtp2] finished (3 left) 2016.05.17 16:51:46 LOG6[22]: ssl_start: s_poll_wait: TIMEOUTbusy exceeded: sending reset 2016.05.17 16:51:46 LOG5[22]: Connection reset: 0 byte(s) sent to SSL, 0 byte(s) sent to socket 2016.05.17 16:51:46 LOG7[22]: Local descriptor (FD=16) closed 2016.05.17 16:51:46 LOG7[22]: Service [ssmtp2] finished (2 left)

when a user is sending an email.

The email actually makes it to our mail server and gets sent, but the sender’s mail app says that it could not be sent.

Upgraded to 5.33b2, no change.

It is not all the time - I suspect it is with emails with large attachments.

Any suggestions?

Mac OS X 10.7.5.

Thanks,

James.
