Hi, we found recently that we had a problem with /mail/tmp/L.mbox used by upasfs to lock.
Looking into, we found that in upas/common/libsys.c the function generating the lock file name returns always "L.mbox" but not .../L.<mbox file name> as it seems it should. Also, the function doing the actual lock hides the error string. I copied our changed file to /n/sources/contrib/nemo/libsys.c Didn't create a patch yet because I'm not sure it's the right change for this problem.
