RouterOS v7.6 Fail to establish BGP Session

RouterOS Forwarding Protocols
1

When establishing BGP Session we get the following error message: Write to bgp failed (32) { #buf=1 max=64 sk=Socket{ 5 a } }

We have an existing BGP session to another peer which is working just fine, we are receiving around 138 000 routes on this session.
We are now trying to establish a second BGP session where we expect to receive another 180 000 routes, however this session fails with the above error message.

This issue was introduced with 7.5, and still happening with 7.6:
http://forum.mikrotik.com/t/v7-6-stable-is-released/161553/1

It was reported to be fixed, but is still appears in the current 7.7 beta

For our three CCR2216, we had to go back to 7.4.1 to have BGP working.

Memory limit is unrelated to this OP problem.

Check if for second BGP session local address is picked correctly.
