We found a bug where geoserver grows basically unbounded (32GB+) when using hdf5, while the java heap and native heaps stay small (2GB and 300MB resp). The bug still exists in the current version of netcdf-java. The main symptom is unfortunately not noticeable with JVM tooling: a lot of mmapped segments of around 64K each appear when you look on linux with pmap.
I hacked a fix in the cdm-4.6.15.jar library. A test scenario that crashed the server in minutes now runs for an hour straight without growing the process RSS size. I logged a bug in both projects (the geoserver one is pretty minimal). https://github.com/Unidata/netcdf-java/issues/1138 https://osgeo-org.atlassian.net/browse/GEOS-10831 Hans Yperman Department IT [cid:ee5bc098-e589-409a-a234-33833a88f9c7] Vlaams Instituut voor de Zee vzw InnovOcean Campus, Jacobsenstraat 1 8400 Oostende, België ☎+32 (0) 59 33 61 13 📧 hans.yper...@vliz.be<mailto:hans.yper...@vliz.be> www.vliz.be<http://www.vliz.be>
