ADDITIONAL SYSTEM INFORMATION :
Ubuntu 22.04.1 LTS (GNU/Linux 5.15.0-1031-azure x86_64)
Jdk 20.0.0 from java.net

A DESCRIPTION OF THE PROBLEM :
After running for 30/40 minutes vms crash with this message. Seems related to G1.

We are currently running without any crash with jdk 18.0.2.

We first saw this error with jdk 19.0.0, which happened a lot more occasionally (maybe once every day or 2). After the error happened a few times we reverted to 18.0.2

Now we have tried with 20.0.0 and 2 VMs crashed in less than 40 minutes.

We cannot reproduce the error locally or in the test environment. We do have an extensive suite of end to end tests, but the error does not happen there (it runs for 7 minutes).

REGRESSION : Last worked in version 18

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Cannot provide a minimal reproducer, just run the web application with jdk 20.0.0 and the system crashes after some time (about 40 minutes)

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The JDK should not crash. We haven't had any crash with jdk 18.0.2
ACTUAL -
System crashes

---------- BEGIN SOURCE ----------
Can't provide source code. I can provide a couple of recent crashes (hs_err....log and hs_err....jfr files)
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Downgrade to jdk 18.0.2

FREQUENCY : often
