[Archivesspace_Users_Group] Server leaking resources? Slows after running a while.

[Zachary L Pelli]

Thanks for the response,

Java 1.7.0_181 running on RHEL 7.4. Maybe I’ll try updating to Java 1.8, but I’m not confident that will fix it.

Regards,
Zach

Zach,

What version of Java, ArchivesSpace, and OS are you on?  We were seeing the same issues, but after upgrading to Java 8 (on CentOS 6 w/4GB RAM) with AS 2.5.0, it has been well-behaved.

Hope that helps (and that I didn't just jinx us),
Jason

Hey all,

We’re having issue with our installation and I’m trying to narrow down what the problem is. After the application starts, it runs smoothly. After s few days, maybe a week, it slows to a crawl, frequently throwing 502 errors. I forgot to grab the logs before resetting, but I’ll be sure to check them next time it happens.

I have set the java heap space to 2500mb on a server with 4gb total memory. Running top command when the server was slow showed a constant 100% CPU usage and ~80% memory usage. After resetting, it shows 1-20% CPU usage and ~38% memory usage.

I have a feeling that  it may be time to upgrade to a more powerful server but I want to rule out any application-related issues before making that leap.
