Problems with SMTP connection re-using (SSL read: error:00000000:lib(0):func(0):reason(0))

Hello,

I'm just having this problem. I successfully sent an email with libcurl and the connection stays open (first line). Then I try to send another one:

...
2012-12-06 15:33:49 : CURL: Connection #0 to host smtp.xxxxxxxxxx.com left intact
2012-12-06 15:34:59 : CURL: Re-using existing connection! (#0) with host (nil)
2012-12-06 15:34:59 : CURL: Connected to (nil) (80.67.29.4) port 25 (#0)
2012-12-06 15:34:59 : CURL: MAIL FROM:<qa1_at_xxxxxxxxxxx.com>
2012-12-06 15:34:59 : CURL: SSL read: error:00000000:lib(0):func(0):reason(0), errno 54
2012-12-06 15:34:59 : CURL: SSL_write() returned SYSCALL, errno = 32
2012-12-06 15:34:59 : CURL: Closing connection #0
2012-12-06 15:34:59 : CURL: Failure when receiving data from the peer

Any idea why it complains with SSL read: error:00000000:lib(0):func(0):reason(0), errno 54?

Am I doing something wrong here?

But occasionally it is working, but I don't know the reason (same code, same smtp-server, same user):

...
2012-12-06 15:40:00 : CURL: Connection #0 to host smtp.xxxxxxxxxx.com left intact
2012-12-06 15:40:47 : CURL: Re-using existing connection! (#0) with host (nil)
2012-12-06 15:40:47 : CURL: Connected to (nil) (80.67.29.4) port 25 (#0)
2012-12-06 15:40:47 : CURL: MAIL FROM:<qa1_at_xxxxxxxxxxx.com>
2012-12-06 15:40:47 : CURL: 250 OK
...
