Crashing on login

[shaggi7]

Hi, I am facing the issue upon login into ejabberd :

$ ejabberdctl live
--------------------------------------------------------------------

IMPORTANT: ejabberd is going to start in LIVE (interactive) mode.
All log messages will be shown in the command shell.
You can interact with the ejabberd node if you know how to use it.
Please be extremely cautious with your actions,
and exit immediately if you are not completely sure.

To exit this LIVE mode and stop ejabberd, press:
  q().  and press the Enter key

--------------------------------------------------------------------
To bypass permanently this warning, add to ejabberdctl.cfg the line:
  EJABBERD_BYPASS_WARNINGS=true
Press return to continue

I have also tried the solution provided in #3037.

also I am receiving the these presence stanzas from rosters upon login:

<presence xmlns="jabber:client" xml:lang="en" to="tony@192.168.4.69/webApp" from="bob@192.168.3.145" type="error">
    <x xmlns="vcard-temp:x:update">
          <photo>4e354a5e2baf2f5d3f055529561fed9536cb037b</photo>
    </x>
   <error code="500" type="wait">
           <internal-server-error xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>
           <text xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" xml:lang="en">Internal server error</text> 
   </error>
   <priority>100</priority>
</presence>

Fixed in https://github.com/processone/xmpp/commit/8169533782724615c4b0daa8b9c551f3ce47d032

Update ejabberd, I fixed it:

$ git pull
$ make distclean
$ ./autogen.sh && ./configure --blah-blah && make

[shaggi7]

Thanks @zinid This fix the problem on login. but then i was getting this error stanza

<presence xmlns="jabber:client" xml:lang="en" to="sagar@192.168.4.69/webApp" from="alice@192.168.3.145" type="error">
   <x xmlns="vcard-temp:x:update">
          <photo/>
   </x>
   <error code="504" type="wait">
   <remote-server-timeout xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>
    <text xmlns="urn:ietf:params:xml:ns:xmpp-stanzas" xml:lang="en">
            Connection failed: timeout
    </text>
    </error>
    <priority>100</priority>
</presence>

And then i realized what the actual problem was. Roster information . I not only saves the username of roster but also saves the domain address from which they are connected . Roster were saved using my old IP address . So i removed all roster and then added them back manually.

Yes, don't change domains in the config in order to avoid this.
