Running something like

while ((1)); do { top -n1 -b | tee -a top.log; sleep 30; } done

in a console constantly will give you a log of important details of your 
system. After this happens again, open the file top.log and analyse the last 
output of top, this way you should be able to find out what program / 
plugin / ... causes the problem.

This kind of information doesn't help with finding the cause at all. It's much 
too vague and imprecise. If you really want help, or even getting noticed by 
people who may be able to help, you should prepare more data and more 
carefully. I hope the hint above helps with that. Another tool that might 
help with the analysis: lsof (read the man page - for example type "man:lsof" 
in Konqueror's URL bar - to understand what it does and how to operate it).
