Fixed by PR https://github.com/Unidata/netcdf-c/pull/2316 ?

Since this test is allocating a 500mbyte block of virtual memory, my suspicion is that it is something like the one processor creating the block has to somehow pass (or...

I pass. I have no other ideas about what might be happening. Perhaps someone can apply a debugger or do some profiling to find out.

try this URL: > http:/test.opendap.org:8080/opendap/dmrpp_test_files/ATL03_20181228015957_13810110_003_01.1var.h5.dmrpp#dap4

I will investigate why "dap4:" does not work. The problem is that the URL must somehow inform your client program what protocol to use to access the data: DAP4 in...

One other point. The client program can interrogate the server and determine the proper protocol by looking at the response. But this functionality is not yet published for thredds, and...

Sorry, this may have got lost in my stack. Let me do some checking.

I had the fix, but apparently I got side tracked. Anyway, see PR https://github.com/Unidata/netcdf-java/pull/1255
