Bug ID: 191
           Summary: Sometimes timers (rte_timer) do not expire
           Product: DPDK
           Version: 18.11
          Hardware: x86
                OS: Linux
            Status: CONFIRMED
          Severity: major
          Priority: Normal
         Component: other
  Target Milestone: ---

Created attachment 24
sample timer program

Some timers do not expire as expected. Expiry time has passed and timer is
still in state pending. Other timers installed after still expire as they

Attaching a small test program that installs timers on one core and has them
expire on another to reproduce the fault.

A sample output from the program:

Installed 1000000 timers.
Warning: 4 timer(s) did not expire.

It might take a few runs to trigger the fault, and it might also be easier to
trigger with a bit of background load on the machine.

Has been reproduced on 18.05 and 18.11
