*** Bug 298121 has been marked as a duplicate of this bug. *** From bug 298121: Efter logging into KDE4 my system becomes sluggish for at least 10 - 15 minutes. The problem seems to be that akonadi_agent_launcher claims 1.7GB of my 2GB memory. During the first minute after login akonadi_agent_launcher rapidly claims more and more RAM until 85-90% of my RAM is consumed. During these 10-15 minutes my hard disk is frantically active and my system is in practice not usable. The parent process to akonadi_agent_launcher is akonadi_control. -- Deleting the concerned .dat file fixed the issue for the reporter *** Bug 298626 has been marked as a duplicate of this bug. *** From bug 298626 -- Information about the crash: - What I was doing when the application crashed: My system was completely frozen due to a kernel panic, so I manually powered it down and started again. After boot, I got this crash, restarted the mailfilter_agent, and then got it again. I saw something similar after upgrading from KDE 4.7 to 4.8. I suspect some kind of data corruption or unexpected condition causes mailfter_agent to crash. When this happened before, it took deleting all the local data and then re-importing it to get mailfilter_agent to work again. --- Deleting the concerned .dat file also fixed the issue for the reporter. akonadi_mailfilter_agent is shipped as part of kmail, so I think the product is wrong on this bug. no, the trick above worked also for other Akonadi resources Should be fixed in 4.9.3 with commit b927825 (in kdepimlibs) |
Created attachment 70435 [details] Corrupted .dat file Using master. I suppose the issue appeared because of a short power outage. The symptoms: - The mailfilter agent was using 50% cpu after restart, - The memory usage keeps increasing - The mailfilter agent appears offline in akonadiconsole (despite having Online=true in agent_config_akonadi_mailfilter_agent) - The resource doesn't react to dbus calls. Renaming agent_config_akonadi_mailfilter_agent_changes.dat fixed the issue. and the issue is back as soon as the corrupted file is restored.
