Firefox thread behavior since 2012-06-13-03-05-35
Nightly 012-06-12-03-05-27 (fine) : http://img135.imageshack.us/img135/5378/fx0120612030527.png Nightly 012-06-14-07-59-12 (buggy) : http://img59.imageshack.us/img59/7572/fx0120614075912.png This behavior exists since 2012-06-13-03-05-35 build (2012-06-12-03-05-27 is fine). 1-) Thread name is different. I checked it via "top" on terminal as you can see. 2-) "top" command on terminal shows it fine but it's somehow reporting to KDE's system monitor wrong. See memory usage(shows 2.12 GB, i have 2 GB ram) is wrong but if i look at details(right click -> detailed mem information) it's right. Except that, CPU state is becoming "stopped/suspended" when firefox use %0 CPU. What do you think ? Second issue might be related to KDE's system monitor but it was fine until 2012-06-13-03-05-35 build. Regards. . .
I experience the same and Firefox shows up as "Main Thread" or "RunProcess" in the process list.
Hi. I'm the ksysguard maintainer. It would be great for the firefox guys to fix the name of the process. But I also need to fix the memory problem, and will have a look.
I run the nightly build of firefox, and the process name appeared as "RunProcess". I could not reproduce the Memory problem though. When you see the memory problem again, could you please do: cat /proc/$(pidof firefox)/statm And paste the output? (Please also check that "pidof firefox" also returns the same PID that System Activity is using)

Can you plese do: cat /proc/$(pidof firefox)/status As well? Thanks
We probably just need to avoid call of PR_SetCurrentThreadName("Main Thread") on the main thread and then fix the visual event tracer to specially handle main thread's name. I'll do this on Monday, however anyone feel free to make a patch for this, but please drop a note you do so. Thanks.

The ksysguard problem should be fixed: http://commits.kde.org/kde-workspace/169899ce558f54ad1f37e84c18817b05e90c2ba8
- removed naming of the main thread - visual event tracer explicitly uses Main Thread as name of the main thread - added support for nameless threads in even tracer

Is this commit also included in Thunderbird? I mean is this part of some shared library and I can consider it fixed, or should I open a ticket for Thunderbird?

Thanks for the fix it looks fine but i've just realized that thread name becomed "Runprocess" somehow. Restarted Firefox, it's fine now. I'm gonna try to find a way to repoduce it.

Mozilla/5.0 (X11; Linux x86_64; rv:16.0) Gecko/16.0 Firefox/16.0 SeaMonkey/2.13a1 ID:20120715003006 CSet: a52505700b63 Here too, I see the SeaMonkey executable process change name from seamonkey-bin to (ultimately) RunProcess, as in my earlier comment #12 and as Firefox did for ttaubert in comment #1. I just did the following while the above build (the one I use to type this comment, almost 3 days later than comment #17) was running: linux:~ # echo $(pidof seamonkey) 14173 linux:~ # ps -l 14173 F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD 4 S 0 14173 14171 27 80 0 - 481601 - ? 95:57 seamonkey -P default linux:~ # ps -l --pid 14173 F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD 4 S 0 14173 14171 27 80 0 - 481729 - ? 01:35:59 RunProcess linux:~ # ps -lC seamonkey,RunProcess F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD 4 R 0 14173 14171 27 80 0 - 521555 - ? 01:36:39 RunProcess Notice the difference depending on calling with one PID (and no selection switch) or with a (singleton) list of PIDs (--pid). When selecting by program name (-C) on both "seamonkey" and "RunProcess", only the latter appears. When selecting on only "-C seamonkey" (not shown) ps outputs only column headings, no processes. The PPID points to the script which I use to start SeaMonkey with the correct profile and logfile, as follows: linux:~ # ps -l 14171 F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD 1 S 0 14171 1 0 80 0 - 3270 wait ? 0:00 /bin/bash /usr/local/bin/start-sm-all linux:~ # cat /usr/local/bin/start-sm-all #!/bin/bash (date && seamonkey -P default) >> ~/seamonkey.log 2>&1 &

Confirming for Firefox as well. Process has been started a while ago and is called "RunProcess".
P.S. "RunProcess" is also the process name shown me for this process by the "top" utility.
Please continue commenting on bug 774243 instead. This bug has been fixed and symptoms are now different.
