We're using ext3 on redhat since that's what's supported. Always good to hear/learn from others' experience. We've seen some issues with processes spending a litte too much time in "D" state (as reported by ps) a.k.a. uninteruptible sleep. Not clear what is causing that yet. Seems like a deadlock somewhere. Not in squid. We saw it in apache and others.
