I took a look and I don't know the cause of test hanging and timeout.
I run today more than 200000 iteration of distributor tests and didn't
get a single failure or lock.
David Hunt run the series tests today also, when checking impact on
performance and I guess he didn't got the issue.
@DavidHunt, Am I right?
The failure happened in only one configuration and tests were run by
travis using different compilers, architecture, etc.
The test did not wrote anything on the stdout or stderr:
--- stdout ---
EAL: Probing VFIO support...
APP: HPET is not enabled, using TSC as default timer
RTE>>distributor_autotest
--- stderr ---
EAL: Detected 2 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: Multi-process socket /var/run/dpdk/distributor_autotest/mp_socket
EAL: Selected IOVA mode 'PA'
EAL: No available hugepages reported in hugepages-1048576kB
-------
That's quite strange before the first test that is run: sanity_test,
starts with printing information about the start.
Before that there is only the initialization code of the distributor
structure and creation of mempool.
The only modifications I made to initialization of distributor structure
was initialization of active and active sum fields of distributor:
memset(d->active, 0, sizeof(d->active));
d->activesum = 0;
That's seems not to be the reason.
I don't know what could be.
Is there a way to trigger travis job manually to see if the timeout
reproduces ?

Yes, I got it.
But I interpreted it badly. I downloaded the log and start reading it up
from the end and when I saw:
Compiler stderr:^M
/usr/bin/ld: cannot find -lvirt^M
collect2: error: ld returned 1 exit status^M
I thought that was it. Sorry for that.
BTW I'm going to publish v6 with changes suggested by Honnappa
Nagarahalli (RELAXED memory mode) and David Hunt (indentations)
Best regards
Lukasz
