b config sync all causes active peer to go standby then active?

Hi guys,

 

What we have is a pair of D62s running BIGIP v9.3.1 40.2 in an active/standby configuration.

 

When running a b config sync all from the command line, the active load balancer appears to go standby for about 30 seconds and then returns to active.

 

While this is happening, connections appear to be dropping (even those with connection mirroring).

 

However: a config sync from the web UI doesn't appear to cause the same issue.

 

Because this is a production system, I'm not game to try a b config sync min to see if there is any difference.

 

Has anyone else had the same issue?

 

Cheers,

 

Peter

    is there anything suspicious in /var/log/ltm during that time?

    I've never seen that happen when doing a b load before...

    do you set tmm interface to auto negotiate or fixed speed?
