I have had zopes like that on different linux versions. Following identified reasons on the different installations:
1. LDUF timeout(s) where -1 [...] 2. LinguaPlone had a bug or something, Jodok found this and it's fixed on the trunk. [...] 3. Suspect: CacheFu - Memcache broken [...]
Another thing I came across some times: 4. some method called while working on a request executed a HTTP GET for something else inside the same Zope instance (e.g. via urllib). Have some of these requests running simultanously and chances are pretty big that they'll hang around endlessly waiting for each other to finish and free up a Zope thread to answer their own sub-request. This will typically result in very little to almost no CPU usage. Good luck!
