<div class="">They are large files (1.5GB each), which may be the cause of the problem. If there is a straightforward way to break them up into time chunks then I can do that in the meantime.</div>

<div style="word-wrap:break-word" class="">I have a large set of files (time,level,lat,lon and 6 hourly) that span multiple years, but they are not divided nicely into months/years. I only want to read in one month at a time (and only 00Z), which in some cases,
spans only one file, but in other cases spans two.

<div class="">My code works perfectly for the months that come from only one file, but I get a “Segmentation fault (core dumped)” when the month spans two files. See brief code example below (happy to send more and actual files if needed).</div>
