From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031007 Firebird/0.7 Description of problem: ps -m no longer shows threads. It did in RedHat 9. It looks to me like the /proc entries for the thread are missing? Since I can't tell what PID they have, it's hard to tell, but assuming the next PID would have been allocated, there's no entry for it. On the other hand, if the (numerically) next entry in /proc (which isn't PPID + 1) _is_ the thread, it's weirdly formed - the exe "link" doesn't go anywhere, for example. Run the following python example and use ps -m. On RedHat 9, you'll see two threads, on Fedora Core 1, just the parent. ----- import threading, time def test(): while 1: time.sleep(10) threading.Thread(target = test).start() ----- Version-Release number of selected component (if applicable): procps-2.0.17-1 How reproducible: Always
It appears the problem was that I'd built procps-2.0.17-1 on RH9 (to get the slabinfo commands) and that build was somehow broken against Fedora 1. It's probably a bug in the procps build scripts (like it detects kernel version at compile time rather than run time), but it's not this bug.
