octodns: Error in Ns1Provider

When running ‘octodns-sync’ with ‘–doit’ I get the error below with one of my zones. The command runs fine without pushing the changes.

This might be a bug in the NS1 SDK @weyrick?

It looks to be caused by an excessive number connections for a zone with many records. In the log below I replaced the zone name with example.com, all record names with ‘somerecord’ and removed a range of lines (from the original 110) for visibility.
