otherwiseguyjakeyip: pretty much all the way through. it died after 3 hours in the last stage because I ran out of memory if I remember correctly. Can you get me logs of the entire transaction that gets tried again n=1,idx=0 - n=1,idx=$big number? Because I don't see PgAclAddCommand itself running verify(), I'd like to know exactly what command in the transaction is calling it.13:49

jakeyipotherwiseguy: one more thing to add; I ran out of memory too, had to bump the VM from 8G to 16G to keep going IIRC. This error happens after the MemoryError.22:58
*** mlavalle has quit IRC22:58
otherwiseguyjakeyip: what is your OVS.ovsdb_timeout setting? I think it defaults to 30 and I see in one of the logs you sent me had a timeout at 5 sec...that might also have been one of the many probe_interval settings in neutron/ovs/ovn as well though.23:01
otherwiseguyjakeyip: I've got it running for like the last 5.5 hours on a machine with 64GB ram...23:02
*** ociuhandu has joined #openstack-neutron23:04
otherwiseguyBest I can tell from the python-ovs code, you can also get a TRY_AGAIN on any time sending a command to the ovsdb-server fails in addition to verify(). So any connection timeout that hits, in this case I'm assuming the one from ovsdb-server to the client causing a reconnect and interrupting sending the ridiculously huge transaction with 358k entries in it...23:04
otherwiseguyI'll look into maybe for the sync util itself, going in and temporarily setting all timeouts to 0/infinite. Still haven't noticed the TRY_AGAIN on my side. though it's been running long enough I could have missed it, but every tim eI look it's doing the PgAddPort commands.23:06
*** ociuhandu has quit IRC23:08
otherwiseguyjakeyip: and I don't see those in your log, so I'm assuming they are definitely after where you get hung up.23:09
otherwiseguyjakeyip: regardless of TRY_AGAIN, it seems pretty clear to me that we need to drastically improve the performance of the sync util. each create_port is taking around 2+ seconds. For 12k ports, even without considreing all the port gorups etc, that's around 7 hours.23:14
otherwiseguythat's not running with my indexing patch installed. wanted to get a baseline, but wasn't expecting it to take all day to run.23:15
