CI failed due to UT tests failed(ZMQ related logs)

[msosyak]

The CI is unstable and rarely passed the build stage due to timeout and the following logs

[ RUN      ] BinarySerializer.serialize_overflow
 ERROR:- setData: There are not enough buffer for binary serializer to serialize,                             key count: 1, data length 15, buffer size: 50
[       OK ] BinarySerializer.serialize_overflow (0 ms)
[ RUN      ] BinarySerializer.deserialize_overflow
 ERROR:- deserializeBuffer: serialized value data was truncated,, value length: 11 increase buffer size: 113


***

[ RUN      ] ZmqConsumerStateTable.test

***

# a lot of logs. No new test is started

 DEBUG:> select: enter
 DEBUG:< select: exit
 DEBUG:> select: enter
##[error]The operation was canceled.

For example, for PR #777 only 2 of 8 CI runs passed the build stage(Once before ZMQ was merged)
