We are using GeoServer 2.1.1, so it has GeoTools 2.7.2. Sometimes GeoServer
goes into a state where many WMS requests fail with the exception below. A
restart usually fixes the issue, but that's not desirable from an operational
point of view. So I am wondering how this can happen. Are the
ImageMosaicReaders reused after they are disposed? Are they somehow corrupted
before they are used? Has anybody seen this issue? Thanks!
java.io.IOException: Looks like this reader has been already disposed or it has
not been properly initialized.
