I was thinking the same thing. I am in the process of "manually" backing up my settings (pen & paper) and I am going to reflash with bare minimum needed apps and use claws instead of modest (tho I don't think modest is the culprit, but I'll try anything... It did it again last night, after I went in and renamed metalayer-crawler, changed modest checking from 5 mins to half hour, and disabled auto wifi-search.) I have to believe that it is a result of random tinkering. Also, as per Nathan's advice, I ran top and nothing stood out as using the cpu too much (although maemo-launcher has an asshatload of instances running.) Otherwise, nothing looks very suspect. So, I shall try this. I will post back after a couple days with the (almost) bare install. ... and I have one class 4 Kingston 8gb microsd, but I still boot from the internal 256, so I'm not sure how it could be the culprit. Thanks.
