> I use ATS as a cache server.
> Caching contents are a lot of small size files, image, html, xml and etc..
> Sometimes ET_NET threads go to uninterruptable sleep and no disk I/O occurrs.
> I attach pictures showing the status of threads( by shell command top ) and
> those of disk( by shell command iostat 1 )
> And ATS system uses 2TB disk as a cache and 16GB memory.
