0-20 - Exception occurs when storing stack information

Possible Causes

1. The JVM has set the parameter -XX:+DisableAttachMechanism
2. The specified stack dump path does not exist; in this case, the system will attempt to create it, and a SecurityException may occur during creation, possibly due to lack of permissions.

Troubleshooting and Resolution Steps

1. Check if the JVM has set the above parameter.
2. Check if the account running the service has permissions to create folders.
