Sanjay,

Thank you for reaching out to us about this issue. I'm happy to help you look into this and see what the problem might be.

From what you've pasted, I don't actually see any error messages, but what looks like a series of warnings. From your Confluence server logs you'll be able to find more details including error messages (will start with the word ERROR instead of WARNING) as well as what is causing the error.

It will also help to know what stats your server is running on, including:

Database server and version
Confluence version
Java memory settings (See How to Fix out of Memory Errors for more details on where to find that)
When this last worked normally, and if you made any changes since then.

Thank you for your help!

Regards,

Shannon

Hi Shannon,

Please find following details

1.Database server and version: postgresql 9.6

2. Confluence version: confluence 6.13

3. server configuration

total memory: 4gb

java memory allocated: 1GB(CATALINA_OPTS="-Xms1024m -Xmx1024m -XX:+UseG1GC ${CATALINA_OPTS}")

4. Confluence working normally and we are getting this issue every 30 days once

from the logs, not able to find any errors

Thanks,

Sanjay

Hello Sanjay,

It might be the low memory being allocated, but I'd like to have a look at what comes up in the log scanner. You can find this in the Support Tools & Plugins from your instance.

If you have trouble with that, feel free to send along your log file. You can do so using Dropbox here, and I can scan it for you.

Regards,

Shannon

Hi Shannon,

we have memory 4gb on the server and currently, java heap size allocated to confluence is 1gb and can we increase to 2gb

Thanks,

Sanjay
