I successfully reproduced with openSUSE 11.0.
All beagled-helper cpu load bugs are different, so if you can please provide a few information.
beagled-helper occupy one my CPU core constantly at ~90 %
I am assuming you meant 90% load for more than a few seconds ?
I tried beagle-shutdown, but it do not close beagled-helper only line in log appear:
The log file claimed that beagled-helper was shut down. You by any chance didnt have more than one instance of beagled and beagled-helper running - did you ? These bugs are usually hard to "reproduce". If you still have ~/.beagle/Log/current-IndexHelper could you attach it (it will be a symbolic link to some 2008-*-IndexHelper file). Thanks. If you encounter this anytime in the future, could you send SIGUSR1 and SIGUSR2 to beagled and attach the ~/.beagle/Log/current-* files immediately after that ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I run abuild application to build and rpm and I realise that my system is very irresponsible. I run top to obtain information and I realise that beagled-helper spin constantly about 90% of cpu.

beagled-helper should watch "load" walue and respect it.
It actually does. I suspect this has something to do with rpm. Currently rpm files are indexed by parsing the output of "rpm -q --queryformat ..." so large rpms can be a bit costly. (The rpm process is automatically killed if it runs for too long). Or it was some file whose parser was causing the high load. Usually the file parsers are fixed if the problem can be detected. So if you spot such a file, please report and attach the file. Sending SIGUSR2 to beagled-helper will cause beagled-helper to print the name of the currently indexing file to ~/.beagle/Log/current-IndexHelper -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

No I thought 15+ minutes when beagled-helper load was more than 90%
I tried beagle-shutdown, but it do not close beagled-helper only line in log appear:

In past I had problem that beagle spawn childrens without killing them, so yes from my point of view; it is possible that there were more than one instance running. I will make sure to obtain this information next time.
These bugs are usually hard to "reproduce". If you still have ~/.beagle/Log/current-IndexHelper could you attach it (it will be a symbolic link to some 2008-*-IndexHelper file). Thanks.

Sure I will do that. (In reply to comment #3 from D Bera)

I understand it know. I run abuild, which install 50+ rpms into chroot environment, this will spin beagle to use rpm -q.... Anyway I will provide logs as you requested. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
