I am running reiser4 for a few years now without problems. Yesterday I had an undeletable directory which ls -a reported empty but rmdir claimed not to be empty. There were no kernel messages about it. After fsck-ing I had to run fsck.reiser4 --build-fs (reiser4progs 1.0.7) which finished but printed an error at the very end like "application error" (sorry, I didn't wrote it down). A second run of fsck.reiser4 told me to fix some remaining corruptions using --fix. This worked without error messages and a following fsck told me everything is OK. But then accessing a file froze the process, consuming 100% CPU. I tried cat and cp with same result. The processes could not be terminated nor killed. Still no kernel messages. Only rebooting helped here and a following fsck showed no corruptions. The file could be renamed and deleted which kind of solved the problem. I haven't found (yet) another file like this. Before deleting the bad file I did a debugfs.reiser4 -P to store the metadata so if anyone is interested in debugging this bug contact me to give you the file (34MB bz2). Konstantin
