Hello, we update from Jira 8.20 to 9.12 on Windows server.
Seems like Jira starts fine but when we try accessing it in the browser, it shows the "A page is slowing down your browser", with options to wait or stop. If we "stop", the page suddenly loads. So we can navigate the app but have to wait for the browser to crash each time.
We expect some process is flooding the cache until it is full.
So we increased it in /conf/context.xml to define a `<Resources cachingAllowed="true" cacheMaxSize="100000" />`
As expected, the page is in load mode and RAM used by firefox keep increasing.
The catalina logs seems clean "jira starts successfully", and last line of the access log is:
0:0:0:0:0:0:0:1 716x25x1 - [06/Aug/2025:11:56:05 +0200] "GET /secure/Dashboard.jspa HTTP/1.1" 200 13107 362 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0" "18z7jic"
JVM heap size memory is set to 4GB.
We are running out of ideas. Any help will be appreciated.
