On DPDK application startup, errors may be reported when opening files as part
of the initialization process. This occurs if a large number, for example, 500
or more, or if hugepages are used, due to the per-process limit on the number
of open files.

Implication:
The DPDK application may fail to run.

Resolution/Workaround:
If using 2 MB hugepages, consider switching to a fewer number of 1 GB pages.
Alternatively, use the ulimit command to increase the number of files which can
be opened by a process.

Affected Environment/Platform:
All.

Driver/Module:
Environment Abstraction Layer (EAL).
