Thank you Andre,
On this branch both run_lte.sh and manual testing as documented on the ZeroMQ App Note page work as expected.

Subject: Re: [srslte-users] ZeroMQ failure to connect.
Hey guys,
apparently we've introduced a late bug where scheduling resources have not been allocated properly. This has only affected some conigs, like the default one unfortunately.
We've pushed a fix to [1]. Can you please check if that solves the attach issue?
Thanks
Andre
