Bug ID: 353868
Summary: Sporadic Crashes with Plasma, Plasma Using Too Much
Memory.
Product: kde
Version: unspecified
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-bugs at kde.org
Reporter: phillip9001 at juno.com
Application: plasma-desktop (4.11.11)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.19.8-031908-generic x86_64
Distribution: Linux Mint 17.1 Rebecca
-- Information about the crash:
- What I was doing when the application crashed:
- Unusual behavior I noticed:
Memory consumption would go from 0.7 -- 1.8 GB after a few minutes of idle or
use. This behavior is coupled by the CPU usage going up and down sporadically
until memory increases to and plateaus out at 1.8 - 2.0 GB.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
