I had the same problems, but also with S2S TLS connections (as posted on the ejabberd mailinglist). I disabled zlib support in openssl, now TLS works and doesn't kill the server daemon.(but it's surely not a nice solution)

Dirty solution.

I have the same problem on Gentoo linux.

- ejabberd-1.1.2
- openssl-0.9.7, openssl-0.9.8
- almost any version of erlang from portage
- zlib version 1.2.3 (or -r1, doesn't matter)

After playing with gdb I've noticed, that bug appears in zlib module.

When I emerge openssl without zlib use flag, this bug vanishes.

I think this is ejabberd tls_drv.so bug, because other applications that use openssl work fine with stream compression.

Do you use Gentoo too?

Do you use Gentoo, too? Which version of: ejabberd, erlang, xmpp4r, openssl libraries?

A work-around for XMPP4R

I'm having the same problem for weeks now (server is Gentoo, too), sorry for not reporting.

If the XMPP4R client is your own, try the following on a Jabber::Client instance:
client.allow_tls = false

Obviously ejabberd should be fixed, but you may ping me at xmpp:astro@spaceboyz.net for any bugs you find in XMPP4R's (not very complex) TLS code.

Same problem here

I have this problem too on another ejabberd-node. Any debugging information I can provide?

After some more monkeying

sm3.142 — Thu, 12 Oct 2006 22:01:01 +0000

After some more monkeying around I've noticed a different manifestation of the problem where glibc catches an invalid pointer and provides a backtrace. For different runs of the same problem I get mostly the segfault version and sometimes this. Something is well and truly botched.

Just for good measure, I

sm3.142 — Thu, 12 Oct 2006 21:57:36 +0000

Just for good measure, I also tried with Erlang/OTP R11B-1 and Erlang/OTP R10B-10. Makes no difference.
