The vmkernel.log shows the following repeated log entries.
pf_free_state: delayed for state(XXXXXXXXXXXXXX) id:XXXXXXXXXXXXXXXX timeout:25 (Expected 25) refcount:1 (Expected 1) ens_refcount:1 (Expected 0)
You can suppress the log entries with the following commands:
esxcli system syslog config logfilter add --filter="1|vmkernel|pf_free_stateā
esxcli system syslog config logfilter set --log-filtering-enabled=1
esxcli system syslog reload
We recommend opening a support request with Broadcom to investigate the root cause of the log entries.
