hi, everyone

We intend to use moosefs at our product environment as the storage of
our online photo service.

We'll store for about 400 million photo files. So the master server's
mem is a big problem.

I've built one master server(64G mem), one metalogger server, three
chunk servers(10*1T SATA). When I copy photo files to the moosefs
system. At start everything is good. But when the master server's
exhaust the memories.  I got many error syslog from master server:

Jun 21 11:48:58 mfs-master[4166]: currently unavailable chunk

and some error message like this:

It's a memory problem or a kernel tuning problem? Anyone can give me
some information?

Thans all.
