i updated the database for epics channels for the PSL lab and restarted the framebuilder on fb1.
I didn't restart the framebuilder on fb0, but once it will be restarted it' will load the new channel list too.

I saw that something seems to be wrong with the network as we have several lost packets which also shows up in the saved data.
I will investigate this later as it seems to be a problem for the slow channels from the PSL lab only.
