[stunnel-users] TIMEOUTBusy exceeded

[James Brown]

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[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.
