Recently we had a thread about experiences with migration from Fedora to RHEL WS or CentOS / Scientific Linux. I would like to move the other way. Since an upgrade from RHEL WS 4 to 5 the machines continously freeze two times a day or more, even when idle, applications are crashing (esp. Evolution). It's no joy. I couldn't find anything specific which could cause the crashes. Question: Has someone done it and might share his / her experience? Peter
