Any performance improvements with a larger LDM queue? The grid log will show you which files are crashing the JVM, I suggest disabling those models in pqact.conf. I've seen this happen with the NDFD and I'm not sure why. Which other models cause core dumps? With 15.1.3 there are new pqact.conf entries for a number of models, with a default set enabled and most regional, ensemble, and duplicate models disabled. The master set of grids to ingest to EDEX (including most regional models) is https://raw.githubusercontent.com/Unidata/awips2/unidata_15.1.1/rpms/awips2.upc/Installer.ldm/patch/etc/pqact.grids I'm able to process this entire set on a server with 16 cores, 24 GB memory, and 1 TB SDD disk. But if I turn on other feeds, especially NEXRAD3, I have to pare down the number grids I'm ingesting or everything backs up. Hence the default set in 15.1.3 pqact.conf. .
