i've been having some problems with our mailman installation at the office. it's mailman 2.0.8 from the debian package (so the installation is a bit weird, to conform with debian policy etc. etc.), but seems to work pretty well most of the time.
the archives are from an older mailman installation, and are mounted over NFS on a filer (which tends to crap out occasionally). i'm moving the files to a slightly less crappy filer, which might help somewhat...
anyway the problem is that there are lock files, which don't have a date or time on them. if i create files in that directory, they have a date / time as they should, but the lock files look like: -rw-rw-r-- 2 list list 41 Mar 29 2002 adm.lock -rw-rw-r-- 2 list list 41 Mar 29 2002 adm.lock.ladd.9136 -rw-rw-r-- 1 list list 41 Mar 29 2002 adm.lock.ladd.9249
if i do: % touch booger i get: -rw-r--r-- 1 root list 0 Mar 29 17:26 booger
my guess is this is because of NFS. the time on the two machines is synchronized via NTP, so the time on both machines is the same. the locks directory itself (and all of the other mailman directories) are on a local drive - just the archive and mbox files are mounted via NFS.
generally, removing the locks fixes the problem (which happens once or twice a day).
