---------------------------------------------------------

OK, close this issue.
On our networks, we can't change ATS 3.2.4 to 5.0x. Because it needs a lot of time and cost.
So we have to keep this environment for a some time.
Is it OK that I reopen this issue if enough information will be found in the future?

> I use ATS 3.2.4 as a cache server.
> Cached 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 occurs.
> 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.
