LDP SC Entity Manager error

[Anatoly_Machekh]

Hello,
We have in lab two connected x460 (EXOS 16.1.4.2) switches with MPLS/LDP/VPLS between. When I enabled logging for event MPLS.LDP.InternalExcept I can see following messages:

Feb 2 11:28:06 10.1.2.1 0x00002301-48 (0) LDP SC Entity Manager received a socket error indication. Error code = 22
Feb 2 11:28:21 10.1.2.1 0x00002301-48 (0) LDP SC Entity Manager received a socket error indication. Error code = 22
Feb 2 11:28:51 10.1.2.1 last message repeated 2 times

Could not find explanation for this error. What does it mean?
Regards,
Anatoly

One more piece of information I missed previously - this error is seen when LDP is down between switches.
