Closed YoungjaeKim closed 5 years ago

YoungjaeKim commented 5 years ago

Hi. I changed Slack OAuth Access Token in Administration and it throws TeamCity error when I click Save button. my server has 50% memory usage (more than 200MB free memory)

TeamCity Diagnostics shows 100MB memory increases after the crisis.

Do you have any idea?

The version above was 1.1.7, and I confirmed that 1.1.8 works fine.
