Hi,

From the bug description and screenshot, the issue happens once after the system was installed on a bare metal server (Simplex). ovs-vswitchd processes that you suspected are running in background when 1st time the system was booting up (so more like a memory used up rather than memory leak). Correct?

I'd like to check whether and how OVS supports multiple ovs-vswitchd processes (which seems abnormal to me). Would you please kindly provide the following details which may help with the triage? 1. kernel version and OVS version that you're using; 2. OVS or OVS-DPDK; 3. full screenshot (with full cmds) and additional OVS logs if possible. BTW, 1. can manually killing all OVS processes followed by starting/configuring an OVS instance/daemon work around the issue? 2. does anyone have a remote debug environment so that we could better look into the issue? Thanks!
