Pls help: monitor status flips

Hi all,

 

 

We're using BIG-IP 6400 (BIG-IP Version 9.4.7 320.1). We defined pools for all nodes' port 389 (ldap) and 0.

 

 

Each node is monitored by gateway-icmp. ldap pool members are monitored by ldap monitor while the "port 0" pool is monitored by gateway-icmp.

 

 

Although the services work properly, we note that in /var/log/ltm, monitor status flips regularly without marking the service status up/down respectively, e.g.

Thanks a lot.
