Adding VLANs is flaky on 5412zl

[Techops]

I am having the strangest problem with my 5412zl. I need to add vlans that are all using one single DHCP server. I add a vlan, give it an IP address, like 10.103.0.1/16, and add a helper-address, like 192.168.20.2.

I created vlans 103 to 109 and 111 to 115 in this way. When I add a port to a VLAN, command "untagged g20" in the appropriate VLAN context, the workstation on this port should pick up an IP address from 192.168.20.2.

The problem is, this does not work consistently across all these VLANs. In my case, from 103 to 115, only 108, 109, 111 and 113 worked, while the config is exactly the same. The only way to fix this is to reboot the switch after the vlans have been created, but that is obviously not a production solution.

The firmware is K.13.09, ROM K.12.12

The switch config is below, your help would be greatly appreciated.
