Red Hat Bugzilla – Bug 1350816
proc.psinfo.rss is incorrect with threads enabled
Last modified: 2016-09-05 22:19:57 EDT
Description of problem: When using -L with pmdaproc threads are listed as expected for proc.psinfo.pid and others. However, at least for proc.psinfo.rss some values reported are impossible: $ top -b -n 1 | grep firefox 7855 testuser 20 0 2027664 661412 69580 S 0.0 8.4 14:42.15 firefox $ pminfo -f proc.psinfo.rss | grep firefox inst [7855 or "007855 /usr/lib64/firefox/firefox"] value 660672 inst [7872 or "007872 /usr/lib64/firefox/firefox"] value 660672 inst [7873 or "007873 /usr/lib64/firefox/firefox"] value 4008509440 inst [7874 or "007874 /usr/lib64/firefox/firefox"] value 4008509440 inst [7875 or "007875 /usr/lib64/firefox/firefox"] value 4008509440 inst [7876 or "007876 /usr/lib64/firefox/firefox"] value 4008509440 inst [7877 or "007877 /usr/lib64/firefox/firefox"] value 4008509440 inst [7878 or "007878 /usr/lib64/firefox/firefox"] value 4008509440 ... First observed by lukas` on IRC.
Pretty sure this is related to the command field in files like /proc/pid/[task/]stat containing whitespace - certainly several of the firefox threads on my local system show this behavior anyway, and its definitely confusing the code. I'm pushing a fix for that into pcp git now, but it'd be good to confirm the contents of some of the thread procfs files from one of your affected systems too Marko/Lukas - thanks.
The patch fixes the issue for me. Thanks!
