Mysterious Core Dump

[Ian Coleman]

I'm trying to sell JIRA & the Agile plugin to my boss, so I've downloaded and installed JIRA on a Digital Ocean droplet with 1GB of RAM and 30 GB SSD. It's a bit slow, but usable. One problem I've run into is that it occasionally just dumps core.

catalina.out doesn't log anything problematic as far as I can tell, but if I run with jira-run.sh -df things work fine for a while, then I get unceremoniously dumped to the command prompt as follows:

Killed (core dumped)

I'm kind of at a loss to know where to begin to debug this. Does anyone have any suggestions?

Thanks!

That pretty much says Jira is being killed from the outside by something else. If it were Jira falling over and creating a core dump, you'd have a load of other stuff going into the log, and almost certainly nothing saying "killed".

I'm afraid you need to look at what your root users and operating system are doing - it sounds like something is deciding to kill Jira for some reason.

(On the "slow" point - it's really good to put Jira's index on an SSD - that has doubled or tripled parts of the performance stats I've seen, but the memory. That's a bit low. How much are you giving to the JVM running Jira and how much are you leaving for the operating system to use?)
