Re: Artemis server getting killed randomly by OS Kernel

2022-09-19 Thread Jan Šmucr
I can't see one very important point being mentioned and that is non-heap memory consumption. Does your metric tool cover the entire instance memory consumption, or is it monitoring just Artemis heap? A rule of thumb is to have Xmx somewhere around the half of the entire memory available for the

Sad part is I am not seeing any logs with paging or when the broken is getting killed. There are simply no logs, the only logs I see are before the process got killed. Last log I see in Artemis.log is console is up and available. That’s it. Thanks Ekta Awasthi, Engineer, EAI Operations & Suppo

I would recommend check if your system is paging.. and how many destinations are paging... 2.25.0 offers a significant improvement in paging. On Mon, Sep 19, 2022 at 3:31 PM Ekta Awasthi wrote: > > Hello, > > Thanks for your response on this issue. > > Artemis is the significant process sitting o

Hello, Thanks for your response on this issue. Artemis is the significant process sitting on my system with -Xms2G -Xmx6G. At the time instance was running it was hardly hitting 3gb is what I could see from monitoring tool so not sure why artemis is getting killed. If any thoughts, please shar

By default the oom killer will always target first the biggest process. You'll need to monitor your global memory consumption and check if it is not being eaten by a swarm of little hungry processes. If artemis is the only significant process sitting on your system, check first the -Xmx value pass

Ekta, this sounds like an issue worth discussing. However, it doesn't seem directly related to Michael's question. I recommend you start your own thread about your issue rather than using this thread. Thanks! Justin On Mon, Sep 19, 2022 at 12:53 PM Ekta Awasthi wrote: > Hello, > > My apache ar

Hey, Michael. This is definitely the right place to seek help. Please provide details about the crash (e.g. high-level overview of what your applications are doing, broker configuration, broker logs, etc.) and we'll see what we can uncover. Justin On Mon, Sep 19, 2022 at 12:39 PM Michael Brennoc

Good day, I was hoping to ask some of the more experienced Apache Artemis why my server keeps crashing after a few hours. I'm running Artemis 2.19.1 on the default settings on an IBM AIX box. I can provide a copy of the stacktrace, but it doesn't have much information. I'm also trying to be carefu

To isolate different sets of services they run on separate artemis instances, and to avoid concern spilling into the application layer a limited number of queues have core bridges to other artemis clusters in the same datacenter for cross communication. The dual mirroring on the other hand is f

Sorry, I thought we were already on the same page. Clebert, there was a workaround for the MySQL bug which was a change to the connection string to not enable multi-host/replication. I have filed the bug with MySQL Connector/J with a minimal proof of concept (based on the affected artemis-jdbc c
