I think this is the same as #43
Looks like the workaround I did is not good enough. The data race is fixed in Jaeger (I submitted the patch earlier), we need to bump our Jaeger dependency to the latest (but it is not trivial as explained in the linked issue).

[tigrannajaryan]

One possibility is to increase the pause in the workaround code to reduce the chance of the failure even more (obviously it is not a proper fix, but may be the reasonable thing to do if updating Jaeger dependency is too costly).

[pjanotti]

We should look into upgrading Jaeger: we removed some dependencies and now it may not be so hard.

This was fixed quite some time back, closing it.
