AW: [mapserver-users] mapcache in a cluster

[Eichner, Andreas - SID-NLKM]

We use TileCache.py on two servers with the cache on an OCFS2 on a
shared LUN in the SAN. No known issues with that for now. Note: Spurious
stale lock files occurred already on a single machine. There seemed to
be issues with lots of requests and a very slow upstream server. I used
a cron job to delete lock files older than 5 minutes or so.
As Thomas noted, if the lock files are created on a shared filesystem
and you make sure the filesystem you use is able to lock files properly
(read the docs carefully!) there's no reason why it should not work.
