ServerRunMode.FORKED always leaks running server processes when cluster shutdown fails -------------------------------------------------------------------------------------- Key: ISPN-12368 URL: https://issues.redhat.com/browse/ISPN-12368 Project: Infinispan Issue Type: Bug Affects Versions: 11.0.3.Final, 12.0.0.Dev04 Reporter: Radoslav Husar Assignee: Radoslav Husar Priority: Major See WFLY-13897 for the 'reproducer' in WildFly. This is due to a couple of things: 1. Obtaining PID in JDK8 is not implemented. 2. Obtaining PID is broken in higher JDKs due to ISPN-12366. 3. The obtained PID is wrong anyway, because its the PID of the parent shell process, not the child server process. 4. The kill command usage is incorrect and fails anyway. The fix is to assign random UUID to a server process and filter properly.
