Leif Hedstrom commented on TS-3028:
-----------------------------------
There's not a whole lot of details here. Have you tested this with our latest
versions? 5.0.x?
Also, v3.2.x is an unsupported version, so no future work will be done on this
release.
> Some ET_NET threads go to uninterruptable sleep with empty disk I/O

> 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.
