Comment(by webmeister):

 > Hm. Is this host running with a very small HD? Are you nearly out-of-
 space on it?
 It is a small disk, but there is plenty of free space:
 {{{
 Filesystem      Size  Used Avail Use% Mounted on
 rootfs           15G  685M   14G   5% /
 }}}

 > It would help to have the (compressed!) contents of cached-*desc* from
 the /var/lib/tor directory.
 I'll wait for the error to occur again and then collect the files. In the
 meantime I can at least provide the file /var/lib/tor/unparseable-desc
 that has been created the last time I restarted Tor after the error. The
 log messages in this case read:
 {{{
 Jan 11 20:31:19.000 [notice] Reloaded microdescriptor cache.  Found 9004
 descriptors.
 Jan 11 20:31:35.000 [warn] crypto error while reading public key from
 string: bad end line (in PEM routines:PEM_read_bio)
 Jan 11 20:31:35.000 [warn] parse error: Couldn't parse public key.
 Jan 11 20:31:35.000 [warn] Error tokenizing router descriptor.
 }}}
