/export hangs

I habe two Mikrotik routers, one CCR1009-8G-+S-+S+ and one RB3011UAS, both running at 6.4.4beta61 . On the RB3011UAS the /export command hangs in compact and verbose mode. “/system backup save” works fine

The last command output by /export are (some values replaced by …):

/ip dhcp-client option
add code=60 name=vendorclassid value="..."
add code=61 name=clientid-voip value=0x...
add code=12 name=hostname-voip value="'..."

But this problem i snot new to this version of RouterOS. I have this problem since a longer time and hoped it would be fixed by the next update. But I forgot about it and di dnot report it as obviously the next update did not fix it (this is many updates ago :wink: ).

How can I solve tzhis issue?

Send an email to support@mikrotik.com with all the necessary details.

Yeah, thank you. Doing it by contacting support is my usual procedure. I decided to give the forum a try this time as it is not urgent. It only hangs my automated backup procedure but I can bypass that.But you are probably right, better to go for the support path.
