Re: Hazelcast instance not active


Hi Jason, indeed, upgrading the instance is very high on the priority list.  This is a server that we have taken over.  It had been compromised previously on Linux with a well known bitcoin mining zero-day vulnerability affecting out of date struts instances.  That has since been sorted out.  A second server running Windows has not been affected.  We had migrated this machine to a Windows box as a short term solution since the zero-day script was written to specifically target Linux.  Since Upgrading is a time consuming process, we are scheduling it for ‘as soon as possible’ beginning this weekend.  It will happen off-line, incrementally, until we are up to date but it’s not likely to be complete in the next few days.
For now, is there anything obviously amiss in the reported output from ‘about DHIS2’?

Hi Edward,

You would be well advised to upgrade that instance as soon as possible. There are  number of very serious security issues which have been fixed in later versions, but not as far as I know, as far back as 2.16. It would not surprise me at all of your server had been compromised, which might explain why this is happening. I would carefully check the server logs for any strange activity, but would recommend that you upgrade to a later version as soon as possible, where a number of security problems have been recently rectified.

For the past two days I’ve woken up to this after logging in to DHIS2 (2.16) on Windows:
HTTP Status 500 - Hazelcast instance is not active!
I’m not sure what’s causing it and I need to investigate the logs but I wondered if anything obvious comes to mind from the user group – has anyone else experienced this and what should I look out for?
I’ll reboot the server (sorts it out) and continue with some urgent work then investigate what may be causing this.
