rakhmerovkong: hi, I left one small comment in your patch with REST API07:58
rakhmerovplease fix it and I'll give my +207:58
rakhmerovhparekh: hi Hardik, you here?08:01
hparekhrakhmerov, hi08:01
rakhmerovI found one problem with WSGI service and thought you could maybe help me understand something08:02
rakhmerovso now our API works as a WSGI service (comes from oslo.services) and it forks some number of worker08:03
rakhmerovworkers08:03
rakhmerovsometimes, if we send an API request and it takes longer than ~15 seconds to process it (e.g. a heavy DB query) then WSGI service just kills corresponding worker08:04
rakhmerovw/o even logging anything about the reason08:04
hparekhoh08:04
rakhmerovhparekh: sounds any familiar to you?08:04
rakhmerovyes08:04
rakhmerovit's pretty confusing08:04
rakhmerovI just basically do 'mistral task-list' and if a number of tasks is pretty big (~3000) then it kills a WSGI worker08:05
hparekhrakhmerov, Give me sometime. I will update you08:05
rakhmerovso the timeout is about 15 seconds which doesn't seem anything like in oslo.service config options (in their defaults)08:06
rakhmerovyeah, thanks08:06

hparekhrakhmerov, Hi, I am unable to reproduce it in my devstack environment. My wait time is almost ~30 seconds.09:43
hparekhI have test this with action-list with action definitions in database are ~1200009:44

rakhmerovhparekh: hm... this is strange10:21
rakhmerovmaybe it depends on an operating system10:21
rakhmerovhparekh: how do you organize a load on a worker?10:22
rakhmerovmaybe this worker just runs out of memory or something like this, I don't know10:22
hparekhrakhmerov, I use ubuntu trusty.10:29
rakhmerovok10:29
hparekhI have just run mistral action-list command after loading data to action_definition table10:29
rakhmerovok, and your methods works about 30 seconds?10:30
hparekhyeah10:30
rakhmerovI mean is it really such a heavy query that it takes 30 secs?10:30
hparekhI took 30 seconds to complete10:30
hparekh*It10:31
openstackgerritHardik Parekh proposed openstack/mistral: Added unit tests for Workbook and Workflow filtering  https://review.openstack.org/36727210:31
rakhmerovhm... I see10:32
rakhmerovhparekh: thanks a lot, I'll keep investigating. But seems like it's related to operating system or some memory settings10:33
rakhmerovI guess it might run out of something (like memory)10:33
rakhmerovguys, is anybody available to investigate https://bugs.launchpad.net/mistral/+bug/1621039 ?10:34
