Dup of bug #138982 This is a javaws bug, not glibc bug. http://www.opengroup.org/onlinepubs/009695399/functions/waitid.html mandates that options is formed by OR'ing together one or more of the following flags... but javaws uses 0 for options. Note one or more, not zero or more. The difference from FC2 is that starting with FC3, glibc uses kernel waitid syscall if available, while FC2 used just not very conformant wrapper around waitpid and allowed many broken combinations of arguments. *** Bug 138982 has been marked as a duplicate of this bug. *** |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030701 Description of problem: Installed j2sdk-1_4_2_07-linux-i586.rpm from Sun. When attempting to run any java scripts using javaws provided by that package found 100% of CPU was used by the javaws process and a zombie process had been spawned. Also tried j2re-1_4_2_04-linux-i586.rpm which was used on an FC2 system with the same scripts just fine. Same failure mode under FC3. I did find a similar problem identified as an issue in glibc, apparently in older versions of glibc there was no sanity checking of on the waitid call. As such this would allow the call to complete and execution of the script would continue. I am not sure if this is a problem in javaws or glibc at this point. This does break all scripts using javaws under FC3. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. install java package (any version) on FC3 2. use javaws to execute script 3. Actual Results: CPU running at 100% zombie process spawned Expected Results: Script runs successfully. Works under FC2. Additional info:
