Confluence crashes, login hangs & degrades

Luis Gimilio

Hi, all;

This is my fourth Confluence installation, and it always happens the same. It works OK just after installation, but a few days later, it starts to degrade. Service crashes that need a reboot, login screens that hang up indefinitely, etc.

I've searched through the info available at your site, but haven't found anything that solves this issue. My only option is to reinstall.

We were considering upgrading to a higher license but not if this application isn't reliable. We already use JIRA without issues.

Thank you very much in advance, best regards;

What does the log say? Have you given it enough resources?

Luis Gimilio

Thanks for answering.

As for resources, it's a VM with 4 cores, 8192 MB RAM, and 60 GB hard disk. Should be enough as it's only me who's testing it.

As for logs, a few errors indeed. I'm copying a few lines, but I could zip any file you may eventually need. Right now it's mostly this:

That suggests that Synchrony is not running, or can't be connected to. Is there a separate process running for it?

Luis Gimilio

Yeah. Thing is, this is a completely default installation, so Synchrony should be untouched. Could you help me locating and troubleshooting it?
