[jira] [Updated] (ARTEMIS-6199) Repeated "Cannot find binding healthcheck" and eventual "OutOfMemoryError"
[ https://issues.apache.org/jira/browse/ARTEMIS-6199?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Daniel Martin updated ARTEMIS-6199:
-----------------------------------
Description:
We are seeing a constant flow of error "Cannot find binding healthcheck"; we see it repeat tens of thousands of times and, eventually, the broker runs out of memory (it is possible the two are not connected, but it seems to us that they are).
I know the version I'm reporting this for is a little old, but please don't dismiss the issue out of hand, unless there have been plausible changes that may have addressed it in the meantime.
Here is the tail end of the broker's logs:

> Repeated "Cannot find binding healthcheck" and eventual "OutOfMemoryError"
> --------------------------------------------------------------------------
>
> Key: ARTEMIS-6199
> URL: https://issues.apache.org/jira/browse/ARTEMIS-6199
> Project: Artemis
> Issue Type: Bug
> Components: Broker
> Affects Versions: 2.42.0
> Reporter: Daniel Martin
> Priority: Critical
>
> We are seeing a constant flow of error "Cannot find binding healthcheck"; we see it repeat tens of thousands of times and, eventually, the broker runs out of memory (it is possible the two are not connected, but it seems to us that they are).
> I know the version I'm reporting this for is a little old, but please don't dismiss the issue out of hand, unless there have been plausible changes that may have addressed it in the meantime.
> Here is the tail end of the broker's logs:
> {code:java}
