node-red-node-xmpp crash
Which node are you reporting an issue on?
node-red-node-xmpp
What are the steps to reproduce?
- configure everything
- connect to a MUC room with xmpp in and xmpp out
- shut down XMPP server
What happens?
- node-red service crashes entirely, or
- node-red service becomes unresponsive
What do you expect to happen?
- have the XMPP clients try to reconnect every 10 seconds or so, and...
- ...most importantly: dont let node-red crash!
Please tell us about your environment:
- [ ] Node-RED version: latest (2.1.5)
- [ ] Node.js version: 16.13.2
- [ ] Platform/OS: Ubuntu Server 20.04
- [ ] Browser: Firefox
- [ ] XMPP plugin: latest
Is there anything in the Node-RED log (the console output not the debug sidebar) when it crashes?
I've got this in syslog:
17:10:47 systemd[1]: Started LSB: Start/stop openfire jabber server. NOTE: here I stop OpenFire
Then the thing goes ballistic:

This is not always reproducible, sometimes it keeps spitting out the ECONNREFUSED at an incredible rate, which freezes Node-RED almost to a halt.
One thing I notice regarding reconnection, is that the default reconnect period is 1 second, while the connection timeout of the node is 60 seconds. This might cause at least part of the issues.
The reconnect timeout can be set in packages/reconnect (see https://github.com/xmppjs/xmpp.js/tree/main/packages/reconnect). The connection timeout is hardcoded in the node source code (while I don't know whether this value is actually supported, since I can't find it in the declarations of xmmpjs). I couldn't get a higher reconnect timeout to work by myself yet, though, it remains hammering the reconnect attempts.
xmpp node is crashing node-red I got this on the logs:
"Unknown error: StreamError: policy-violation - Too many unacked stanzas"

After this the system crashes (running on docker).
I believe this started to happen right after a debug node was connected to the second output of a xmpp-in node.
This is a second crash error, just in case it brings more light:

Do you know how your server is configured as that error is due to a limit being exceeded on the server - eg see https://github.com/processone/ejabberd/issues/2615
No details on the xmpp server side, as it's a public server (at jabber.org). I saw the thread you added before posting the node-red crash here and guessed that's the root cause, but I raised the issue cause node-red will enter in a crash loop if the xmpp node is installed and is set to get connected to a server with this config. The weird thing is this happened after 24 hours, when I did some changes on the config of the node; so I guessed the stanza missconfig on the server is affecting the node-red xmpp client only sometimes.
can you paste the complete error stack ? and which version of the xmpp node are you using ? Thanks
xmpp node version 0.6.0
unfortunatelly I cannot get more logs than the ones I posted before, everytime I re-enable the xmpp node enabled, node-red crashes.
These are the lines I got on the last test some minutes ago, logs start when I click on "Deploy" after enabling the nodes:

after this, node-red enters into an endless crash loop (on docker).
OK - hmm - we have event handlers in place for the xmpp object .on("error"... so not sure why it isn't catching them unless the underlying library isn't calling it correctly.
