This ticket was resolved but unless I'm missing something there were no code
changes. I think I'm seeing the same behavior when creating large numbers of
postgis jdbc backed imagemosaic stores using the REST APIs. After creating a
few hundred imagemosaic coverages I start seeing log entries about undisposed
granules in the geoserver log that are noticed during garbage collection.
Eventually geoserver stops responding but sometimes it recovers possibly due to
Finalizer cleanup of catalogs during garbage collection cycles. I back-ported
the fix for GEOT-6039 (#1930) and set the system property
"gt2.mosaic.index.trace" for improved logging (below). I've reviewed the code
committed for GEOT-6605 but it doesn't appear to address the issue identified
by Marco in GEOT-6603. Does anyone know more about this issue and whether
there is a fix? I need to patch a system running geotools 17.1/geoserver 2.9.1.
