            Bug ID: 1636
           Summary: Error reported opening files on DPDK initialization
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: core
          Assignee: dev@dpdk.org
          Reporter: nandinipersad361@gmail.com
  Target Milestone: ---

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).
