Could you explain in more details "something wrong when run everyMinute()"? Do you mean some exception is thrown? Do you have any custom code?

Indeed if the statistics are not collected/cleared periodically it could lead to the impression that the metrics are growing and there is something wrong with the installation, but to investigate it properly we need more details.

I add some code like below, so far, "XMPP Limits exceeded on connection" not appear in the log again.
(1) AbstractMessageReceiver.java , receiverTasks.scheduleAtFixedRate(...), everyMinute() surround with try catch
(2) ConnectionManager.java ,doForAllServices(...), if (service != null) { checker.check(service); }
The problem rarely occurs，I am not sure the fix is valid.

I wasn't asking about your attempt at the fix of the problem but if you had any custom code in Tigase at all.

Could you share complete exception Stacktrace?
