Hi guys,

There is this case, where in certain circumstances the connectivity on IPv6 with remote Esmond server is broken for some toolkit deployments. I have several cases, where this results in data being lost. At the same time the IPv4 connectivity is present and stable, but not used. It could be that there is a timeout, which is defined for the procedure of the data submission with too little time provided for the IPv4 attempt. Or something else.

Would there be a config item allowing me to adjust or configure a balance between the 2 stacks?

How are others dealing with such problems?

Which would be the component that this needs to be reported to?

(I have seen a same behavior from the OPPD component)

Regards,

Ivan, GEANT Ops
