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 ? > Btw, did you receive a notification about this from the robot? 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 > > -- Lukasz Wojciechowski Principal Software Engineer Samsung R&D Institute Poland Samsung Electronics Office +48 22 377 88 25 l.wojciechow@partner.samsung.com
