I know this will not fix your issue, however that might help: - when the core file is generated, if the VA is not in use it should not take space on the disk because it should be stored as a sparse file. Here is an example I have locally (note the 117M allocated on disk vs the 2.6G "virtual" size): bganne@ubuntu1804:~$ ls -lsh core 117M -rw-rw-r-- 1 bganne bganne 2.6G Nov 12 15:34 core Also, if you do not compress it at generation time (via /proc/sys/kernel/core_pattern or similar) it should not impact the downtime as it is simply not written nor processed - if you compress/decompress it with gzip, it will not produce a sparse file but you can 're-sparse' it using eg. dd: bganne@ubuntu1804:~$ zcat core.gz | dd conv=sparse of=core Ben
