Hi all, I have an OVN Central cluster where the leader of the ovsdb NB started to use 100% of CPU load most of the time:
206 root 20 0 11.6g 4.7g 7172 R 106.7 0.3 2059:59 ovsdb-server -vconsole:off -vfile:info --log-file=/var/log/ovn/ovsdb-server-nb.log While in 100% of CPU the read and write operations of the NB cluster is impacted. Doing a debug when there is this increase of CPU load, I can see a jsonrpc reply to a member of the cluster with the size of 460MB, almost the same size as the NB database. I set up an ovn-fake-multinode cluster and imported this database there and the behavior is still the same. At least the leader is not changing frequently since the election timer is in 60secs. And I have already tested with OVN 24.03 and no luck, same behavior. The coverage figures are not so well clear to me: # ovs-appctl -t /var/run/ovn/ovnnb_db.ctl coverage/show Event coverage, avg rate over last: 5 seconds, last minute, last hour, hash=6087dcfb: raft_entry_serialize 0.0/sec 0.000/sec 0.0000/sec total: 59 hmap_pathological 5.8/sec 3.667/sec 3.5750/sec total: 585411 hmap_expand 79729.0/sec 53153.200/sec 51825.3172/sec total: 8484601546 hmap_reserve 0.0/sec 0.000/sec 0.0000/sec total: 48 lockfile_lock 0.0/sec 0.000/sec 0.0000/sec total: 1 poll_create_node 3.6/sec 4.317/sec 4.4372/sec total: 3587083 poll_zero_timeout 0.6/sec 0.150/sec 0.1286/sec total: 105735 seq_change 0.6/sec 0.417/sec 0.4158/sec total: 375960 pstream_open 0.0/sec 0.000/sec 0.0000/sec total: 4 stream_open 0.0/sec 0.000/sec 0.0000/sec total: 3 unixctl_received 0.0/sec 0.017/sec 0.0003/sec total: 11 unixctl_replied 0.0/sec 0.017/sec 0.0003/sec total: 11 util_xalloc 3427998.6/sec 2285349.950/sec 1035236.3394/sec total: 364876387809 100 events never hit Do you guys have any other way to debug it?
