Duplicated messages in `mam_message` about mongooseim HOT 4 CLOSED

Hi,
Check if your library tries to send messages again on the failure.
Check mongooseim logs - maybe something interesting would be there.
We store one copy for outgoing message and one copy for incoming message. Each time we see a stanza routed.

Do you use groupchats?

Thanks for the quick response!

I can't say for sure, but I don't see anything about retries in the documentation. I also grepped xmpp.js source code for retr and saw nothing about retries/retransmitted messages. But I see stream management messages coming from the library when I inspect the websocket connection in my browser, so if xmpp.js was following XEP-0198 properly, it should ack re-transmitted messages and re-transmit them if necessary. I wonder if it could be an issue with their stream management implementation.

Then again, I recall this issue happening in a dockerised setup running locally, so I don't know how messages could be getting lost on the network.

When this happened locally, I could never spot anything suspicious in MongooseIM's logs, unfortunately.

Nope. Just PMs.

It's different. I also disabled stream management on the server and the problem seems to be gone. Gonna close this issue. Thanks for the help!
