Description bill p. (aka google01103) 2010-09-22 12:59:50 UTC
Version:           unspecified (using Devel) 
OS:                Linux

when I restart KDE Lancelot and KDED4 are shown to each be using 100% of one of my processors. Killing Lancelot does not kill the KDED4 process but when both are killed the session runs fine - meaning Lancelot works as it should.



Reproducible: Sometimes

Steps to Reproduce:
see details

Actual Results:  
see details


killing KDED4 does make a change to my system tray, one of the icons changes and the hidden/auto hide attribute of 1 or 2 apps in it are changed

seems to have been resolved in newer updates
Comment 2 bill p. (aka google01103) 2010-11-28 13:11:12 UTC
it's back -both lancelot and kde4 are consuming a cpu's worth of cpu when restarting kde with (alt+ctlr+bksp)squared

running beta 1 of 4.6 (64bit)
Comment 3 Ivan Čukić 2010-11-28 13:37:48 UTC
When you restart the system, does it behave differently?
When you properly log out, and log in, does it behave ok?
Comment 4 bill p. (aka google01103) 2010-11-28 13:51:24 UTC
if I restart the system it is fine

if I logout and log in it is not fine - there is a Lancelot process still running after I do a logout

I can confirm that lancelot does not close after kde logout :

 |-lancelot(2723)-+-{lancelot}(2724)
 |                `-{lancelot}(2728)
 |-lancelot(3407)-+-{lancelot}(3411)
 |                `-{lancelot}(3435)
 |-lancelot(4340)-+-{lancelot}(4343

and so on....

Sometimes nepomukserver does not close too, so when connecting a USB pendrive nepomukservicestub(nepomukremovablestorageservice) and lancelot go to 100% cpu usage:

 PID USER   PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
2723 jef    20   0  239m  20m  15m S  102  2.1   8:10.76 lancelot
2942 jef    39  19 84560  10m 8312 S   96  1.1   7:45.84 nepomukservices
Comment 6 bill p. (aka google01103) 2010-12-17 19:19:31 UTC
interesting(?) note even if I init 3 and then init 5 the problem appears (did the inits to up the graphics drivers)
Comment 7 Ivan Čukić 2010-12-25 10:58:45 UTC
This one should be fixed now (revision 1209158). If it remains with the next 4.6 release, please reopen the report.
