Confluence-6.10.1 causing Linux Debian Stretch to hard-lock during setup

Question

Hello,

I am attempting to run Confluence in a freshly created Linux container (lxc) on a Quad-Core i7 machine, 8GB of RAM with hardware that has been running for years without issue. OS is Debian Stretch, kernel 4.9.0-6, all the latest updates, etc.

I create a new Linux container, install PostgreSQL and then invoke the Confluence installer. After installation is done, I access the default site on :8090 , the installer gets to the point (after creating the admin account) that it asks to create a Space.

As soon as I put a name in and hit create, the machine hard-locks. I've deleted the Linux container and started from scratch several times and the results are reproducible.

The container is not running any other services and when doing the install, there's nothing else running in the background. I even modified setenv.sh to -Xms4096m -Xmx4096m on a subsequent setup, with no difference.

Thank you for the in depth investigation you've done so far. It's very helpful!

I would agree a support ticket is needed here. We'd love to be able to work with the log files from your instance as well as other things that are best sent in a private ticket.

I've created it now for you, and you should be receiving an email shortly.

A member of the Confluence Server team will be able to assist you shortly.

As soon as the issue resolved, it would help us if you could reply here with the resolution so that it may help users in the future. I'll be keeping an eye on your ticket as well.

Take care,

Shannon

Hello Shannon,

On initial setup, I was using the bundled JRE/JDK which is "1.8.0_162".

I spent a lot more time trying to debug this situation and even with a newer JDK I eventually experienced hard lock-ups.  I also updated the kernel version Debian 4.17.8-1~bpo9+1 which still did not help.

Right now I've moved the Confluence installation to a dedicated computer (which is also running Debian Stretch) but installed directly into the host rather than in an lxc container.  So far, that Confluence instance seems to work.

At this point, I think there is some compatibility issue with JRE/JDK 1.8x & running under an lxc container.

I would still advocate for a support ticket being opened ; I bought the 10-user license to get the set up going, but the goal is to scale for a much larger customer.

Hi there,

Thank you for confirming. Apologies for missing that you mentioned your Confluence version in the title!

Can you let me know what version JDK you were using to start with? Confluence 6.10* only supports Java 1.8.

I can certainly file the report for you or see if there's an existing bug. I'll need to know exactly how we can replicate it in order to do so.

Regards,

Shannon
