https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225791 --- Comment #6 from Richard Paul <richard@primarysite.net> --- Okay, with a bit of effort and this is testing against the v0.7.0 ENA driver on FreeBSD 11.1p11 I got a reboot. But this was not easy to get to reproduce. Here's what I did to get this to die.....eventually (it took about 3 hours) * Downsize the instance to an m5.large * I installed nginx on the DB server clone and started it (I'll detail config below) * I installed the phoronix-test-suite and pts/blogbench * I kicked off a backup of our 115GB database to a local (800GB EBS vol.) ZFS partion (the DB is held on a mirrored ZFS set on another pair of 250GB EBS vol's) * I kicked off a stress run of the phoronix blogbench * With two t2.medium instances in the same VPC, I ran wrk -d 12h -c 2k -t2 http://10.0.0.10/ Additional configuration etc.: ---------------------------------------------------------------------------------- root@os-upgrade-test-db:~ # setenv PTS_CONCURRENT_TEST_RUNS 8 root@os-upgrade-test-db:~ # setenv TOTAL_LOOP_TIME 30 root@os-upgrade-test-db:~ # phoronix-test-suite stress-run pts/blogbench Choose Option 3 for Test All Options ---------------------------------------------------------------------------------- ---------------------------------------------------------------------------------- pkg info nginx-full nginx-full-1.12.2_11,2 Name : nginx-full Version : 1.12.2_11,2 Installed on : Thu Jun 28 09:37:29 2018 UTC ___nginx.conf___ worker_processes auto; events { worker_connections 2048; } http { include mime.types; default_type application/octet-stream; sendfile on; tcp_nopush on; keepalive_timeout 65; gzip on; server { listen 80; server_name localhost; location / { root /usr/local/www/nginx; index index.html index.htm; } location = /50x.html { root /usr/local/www/nginx-dist; } } } ---------------------------------------------------------------------------------- ---------------------------------------------------------------------------------- This is just to give you an idea of what we're doing, the backup is actually a whole backups script file for doing this for each database in the RDBMS and they rsyncing to to the offsite server __Postgres dump__ sudo -u pgsql pg_dump -j 16 -Fd dbname -f /var/backups/outfile ---------------------------------------------------------------------------------- -- You are receiving this mail because: You are the assignee for the bug.
