Hello, everyone. Hope you can advise if there is anything I can do to prevent CPU overload that appears to be happening.
Running SuSE 11.4, 64 bit.
Processor (CPU): AMD Athlon™ II X2 240 Processor
Speed: 800.00 MHz
4 GB Memory
Linux 18.104.22.168-0.9-desktop x86_64
Every time without exception that I click “check mail” in KMail (or KMail automatically checks for new mail every 10 minutes) the computer is unable to perform any other function until KMail has finished looking for and then downloading any new e-mail. Any keystroking that I might be doing during this time in another program (e.g., word-processing or entering an URL into Firefox) shows nothing on the screen until after KMail has finished. Once Kmail is finished then finally any keystroking I have done appears on the screen and the computer catches up (returns to normal).
I have opened the System Monitor to observe CPU usage and at the moment I click “check mail” one of the two processors immediately pins at 100%, then drops while, simultaneously, the other CPU pins at 100% (or very close to 100%). The two CPU load lines criss-cross so that while KMail is searching for and downloading mail one CPU is always completely consumed and the other is partially consumed.
It seems absurd to me that KMail should overwhelm the system I have and make it impossible for the computer to multi-task.
Could this be a function of Spam Assassin and Clam AV, both of which are turned on in KMail? Are either or both of these programs such “hogs” that they’re straining the CPU to its limit?
I have noticed that if I highlight any already-downloaded e-mail and label it as “classify as spam,” or click on anything KMail has identified as “spam” and retag it “classify as not spam,” the CPU pegs as previously described and everything else stops.
I have not removed either Spam Assassin or Clam AV as a test because I assume to do so will delete all of the spam-identification and filtering history that’s been done so far.
Can I delete one or both of these programs to check on the resulting impact on the CPU (if any) without losing all of the spam-identification history that’s been built up over the past year and a half I’ve had the computer?
Or if it’s unlikely that Spam Assassin and/or Clam AV are the sources of the CPU overload, what can you suggest I do?
This is incredibly frustrating to have the computer go catatonic until after KMail has completed its search for new mail.
Your thoughts are greatly appreciated.
