            Bug ID: 560
           Summary: excessive numbers of open file handles kept open
           Product: DPDK
           Version: 20.11
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: core
          Assignee: dev@dpdk.org
          Reporter: stephen@networkplumber.org
  Target Milestone: ---

The DPDK memory management of huge pages leaves many open file handles which
may break applications because of running out file descriptors or use of le=
gacy
API's like select that can only handle 1024 fds.

The root cause is in the hugepage segment handling code.

Example.
# lsof -p PID | grep -c rtemap=20
1494

Each fd there is counted twice, once as an fd, and once as an mmap.
So in this case 747 file rtemap files are left open.
