[rabbitmq-discuss] 答复: [SOS] About MQ server connection reset issues

[Li, Chenglin]

Thanks Tim. 

Yes, this log comes from client, sorry.

We found this is a network issue, if network is stable, all is fine. But in
user's environment, we can not make sure network is stable, in this case,
how to handle? Try another times, or other? 


Thanks,
Jack

ideas for this issue? Thanks in advance.

Looking at this - "the server will throw below error log" is incorrect. That
error log comes from the client, not the server.

... and the cause is pretty clear. The connection has been closed. Could
this be a network disruption perhaps? Does your load balancer by any chance
have some threshold after which connections it deems to be 'idle' are
bounced or something like that?


Cheers,
