From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7) Gecko/20040616 Description of problem: I have a rogue java process consuming all of my CPU time. Normally, I'd just kill it. But that doesn't work. Even SIGKILL, which in theory should not be ignorable. That implies that the signal isn't being delivered. But the only time I've ever seen that before is when the process is in D (uninterruptable sleep) state, which isn't the case here. The signal appears to be being sent properly: ps -p 2065 -o user,pid,s,pcpu,pmem,wchan,vsz,args USER PID S %CPU %MEM WCHAN VSZ COMMAND siteint 2065 R 99.9 0.1 - 1197160 /accucard/vbis/j2sdk/bin/java -server -Xms64m -Xmx1024m -Dvbis.root=/accucard/vbis root@asvbis01:~# strace -e kill kill -9 2065 kill(2065, SIGKILL) = 0 root@asvbis01:~# ps -p 2065 -o user,pid,s,pcpu,pmem,wchan,vsz,args USER PID S %CPU %MEM WCHAN VSZ COMMAND siteint 2065 R 99.9 0.1 - 1197160 /accucard/vbis/j2sdk/bin/java -server -Xms64m -Xmx1024m -Dvbis.root=/accucard/vbis According to strace it's not making any system calls. ltrace doesn't show evidence of any library calls either. Version-Release number of selected component (if applicable): 2.6.5-1.358smp How reproducible: Always Steps to Reproduce: 1. Run our java app, and wait for it to use all the CPU 2. Try to kill it 3. Additional info: High severity because it's making the box unusable.
Fedora Core 2 has now reached end of life, and no further updates will be provided by Red Hat. The Fedora legacy project will be producing further kernel updates for security problems only. If this bug has not been fixed in the latest Fedora Core 2 update kernel, please try to reproduce it under Fedora Core 3, and reopen if necessary, changing the product version accordingly. Thank you.
