Hello,-Xmx2048m -Xms2048m - this is a very bad setting. this will induce fragmentation of java heap, which means heap will fail to allot contiguous memory for a large object allocation (greater than 7 MB is considered large). This would subsequently end in an OOM.Ideally -Xms256 and -Xmx1024 could be tried.
