[Stunnel Guru needed] stunnel running, but no longer serve connection after a while ("Dispatching signals from the signal pipe" in logs ==> all stops)
Hi All, I'm really struggling to make stunnel working for more than a few hours. (and the client is yelling hard...) (I solved some other issue : logging per website and making more than one stunnel works) To put it in a nutshell : - stunnel is running and working correctly (I can reach the website in https correctly) - after some hours I get the following situation : - stunnel is still running on linux - trying to connect to a website result in the connection taking very long time and then fails : "*The connection to * extranet.serviceplus-hse.com <http://extranet.website.com>* was interrupted. Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.*" (Chrome) Same symptoms on IE9, Firefox & Lynx (on the server that runs stunnel) (see logs below) - The following logs are the last one seen in the log file : - 2012.04.03 23:33:28 LOG5[24792:140152610346752]: Service extranet.serviceplus-hse.com connected remote server from 127.0.0.1:36256 - 2012.04.03 23:33:28 LOG7[24792:140152610346752]: Remote FD=1 initialized - 2012.04.03 23:33:28 LOG7[24792:140152610346752]: Option TCP_NODELAY set on remote socket - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: Socket closed on read - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: Sending SSL write shutdown - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: SSL alert (write): warning: close notify - 2012.04.03 23:33:41 LOG6[24792:140152610346752]: SSL_shutdown successfully sent close_notify - 2012.04.03 23:33:41 LOG3[24792:140152610346752]: transfer: s_poll_wait: TIMEOUTclose exceeded: closing - 2012.04.03 23:33:41 LOG5[24792:140152610346752]: Connection closed: 186584 bytes sent to SSL, 3275 bytes sent to socket - 2012.04.03 23:33:41 LOG7[24792:140152610346752]: Service extranet.serviceplus-hse.com finished (0 left) - 2012.04.04 06:25:04 LOG7[24792:140152610629408]: *Dispatching signals from the signal pipe * stopping the firewall & fail2ban do not change anything.

Hi Thomas, I was just troubleshooting what looks like a very similar issue. I believe this is fixed in a later version of stunnel, which you can get from stunnel.org and compile yourself from source. This is the ChangeLog entry that I think addresses your problem: - Signal pipe set to non-blocking mode. This bug caused hangs of stunnel features based on signals, e.g. local mode, FORK threading, or configuration file reload on Unix. Win32 platform was not affected. I have just updated from the official Oneiric version to this one, so I don't yet know if it will fix the problem long-term, but I think my odds are not too bad. Hope this helps, -----Scott.
Yes, it helps a lot ! I've another server running a different version of Ubuntu (11.04 where stunnel version is 4.29-1 instead of 11.10 and stunnel 4.35-2build1) Do you think it can work on older version ? I was thinking to try this because I've seen some message about the same symptoms after upgrade so... but maybe the two version are too close and I will need to compile from sources... what do you think about this?

This bug has been corrected in Version 4.38, 2011.06.28, urgency: MEDIUM: - New features - Server-side SNI implemented (RFC 3546 section 3.1) with a new service-level option "nsi". - "socket" option also accepts "yes" and "no" for flags. - Nagle's algorithm is now disabled by default for improved interactivity. - Bugfixes - A compilation fix was added for OpenSSL version < 1.0.0. - Signal pipe set to non-blocking mode. This bug caused hangs of stunnel features based on signals, e.g. local mode, FORK threading, or configuration file reload on Unix. Win32 platform was not affected. however it don't precise from which version it affects stunnel... so my try with 11.04 is a bit risky, even if 4.29 is quite far from 4.38. Maybe upgrading to 12.04 could solve the issue, but I don't like to upgrade right away (I had some bad surpise ;)) so compiling from source seems to be the safest option. Thomas.

Hi Thomas,
I was just troubleshooting what looks like a very similar issue. I believe this is fixed in a later version of stunnel, which you can get from stunnel.org and compile yourself from source.
This is the ChangeLog entry that I think addresses your problem:
- Signal pipe set to non-blocking mode. This bug caused hangs of stunnel features based on signals, e.g. local mode, FORK threading, or configuration file reload on Unix. Win32 platform was not affected.
I have just updated from the official Oneiric version to this one, so I don't yet know if it will fix the problem long-term, but I think my odds are not too bad.
Hope this helps,
-----Scott.

Yep, maybe. I've compiled the 4.53 and it's running for about 36hours, so I guess the issue is fix. Thanks Scott for putting me on the good path ! Thomas. On Mon, Apr 9, 2012 at 16:24, Scott Gifford <sgifford@suspectclass.com>wrote:
