A DESCRIPTION OF THE PROBLEM :
The java process suddenly crashed and exited. According to the error file, it was caused by the actuator obtaining thread status information.

REGRESSION : Last worked in version 21.0.5

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Environment: linux, Ubuntu newer version, openJDK21.02-21.05
First write a springboot java application, which needs to expose the /actuator/prometheus interface (default)
Because the err log display is related to obtaining thread information, it is recommended to have a variable thread pool in the process (the process in question has a nacos client pulling thread)
Then run the java application normally and regularly pull and call the /actuator/prometheus interface.
The crash frequency will not be particularly high. The frequency of our pull is not particularly high, and it needs to continue running for a period of time. We have encountered several situations in the production environment where problems occurred in 2 days, 3 days, or more than ten days.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The JVM process will suddenly crash and exit
ACTUAL -
The JVM process will suddenly crash and exit
