Hello Team! OVS-2.17.7 OVN-22.03.3
We have a cluster of SDBD in 5 Nodes. When we make a load from NBDB/NorthD (making/deleting routers) we observe a strange behavior: * Some nodes (ovsdb-server) of the cluster spontaneously starts in 100% CPU * It could be one or two nodes, not leading, what is remarkable * Leading node and the rest nodes of the cluster remains in 20-30% CPU or even less * This happens for 3-10 mins * Usually, it is causing leader re-election * We have extended election-time for a leader re-election it gets better; re-election is not so frequent; ant yet we are still observing 100% for some node Here are the very confusing lines from the logs for the nodes (ovsdb-server) with 100% CPU utilization: 2023-11-04T07:01:13.447Z|292408|poll_loop|INFO|wakeup due to 1-ms timeout at ../lib/reconnect.c:677 (72% CPU usage) 2023-11-04T07:01:13.448Z|292409|poll_loop|INFO|wakeup due to 1-ms timeout at ../lib/reconnect.c:677 (72% CPU usage) Any clues are extremely appreciated!
