Hello folks, I am somehow managing to create an unkillable process. It is a javavm instance run by an unprivileged user. It happens (most of the time) when I do the following: killall java (a few times when the process is in the state "kserel") killall -TERM java (again a few times) killall -9 java After the attempt to send a SIGKILL, the process the goes into the WAIT state according to top. At this point the process ignores all signals, even from root, and can only be killed with a reboot. If I can provide any additional information, please let me know. Below is the system CV.
