LACP acting up after installing 11.6HF6

Hi,

I've installed 11.6HF6 last week and ever since lacpd shows errors few times a day:

13:30:58 warning lacpd[7996]: 01160024:4: warning: no receive on 2.1 for 45s (timeout=90s)
13:30:58 warning lacpd[7996]: 01160024:4: warning: no receive on 2.1 for 45s (timeout=90s)
13:31:01 warning lacpd[7996]: 01160024:4: warning: no receive on 2.2 for 45s (timeout=90s)
13:31:01 warning lacpd[7996]: 01160024:4: warning: no receive on 2.2 for 45s (timeout=90s)

There are no changes in trunk config. No errors on the uplink switch. Interfaces 2.1 & 2.2 are 10G Fiber.

HF6 shows sol16493's related to LACP changes.

Did anyone else experience any issues with LACP after upgrading to HF6?

Thank you.
