I repeated my tests again with a build from half an hour ago, once on SMP, once with kern.smp.disabled=1. Nothing changed: Copying a 2162 bytes file works fine, copying a 256004096 bytes file locks afs. cmdebug does not return anything. Trying to reboot, I get "init: some processes would not die; ps axl advised". After "All buffers synced", afs got a message for me: afs: WARM shutting down of: CB... afs... BkG... CTrunc... AFSDB... RxEvent... UnmaskRxkSignals... RxListener... osi_StopListener: rxk.ListenerPid ffffff0071a9c000 {2nd try: ffffff005cf3460} WARNING: not all blocks freed: large 0 small 1 All allocated tables... done Nothing new, unfortunately. I could try different file sizes... maybe around the cache size -- would that be interesting? (I have "/afs:/var/openafs/cache:100000" in /usr/local/etc/openafs/cacheinfo. That is in KB, isn't it?)
