OSPF ADJCHG message: Invalid event 1-Way received at Init

Hi,

 

The network has 2 locations with 2* 8206zl core and 5 location with 2* 5308xl switches. All are running OSPF.

On one of the 8206zl locations I receive the following log-messages:

e 03/12/12 11:21:51 03158 OSPF: AM1: ADJCHG:Invalid event 1-Way Received at Init state

Below is the neighbor tabl:

 

# sh ip ospf nei

On the other 8206zl locations I don't see this messages, OSPF nei table below

 

 sh ip ospf nei

10.111.0.9      1   10.111.0.73               FULL     0     6      None  

10.111.0.10     1   10.111.0.74               FULL     0     6      None

10.111.0.13     1   10.111.0.77               FULL     0     6      None

 

As can be seen, this switch is ok, which is on another location.

 

Has anyone seen this before? If so, what can be the solution?

There is no MD5 authentication configured on OSPF for the backbone.

The 8206 are running K.15.06.0008, the 5308 are running E.11.21.

 

Thanks in advance.
