Still experiencing issues with docker containers

[vidboda]

The issue described in VV issue 95 is still happening. I removed the containers (docker-compose down) and rebuilt and ran some tests. I sent about 100 queries to the gene2transcripts operation then the container did not answer anymore. I had a series of errors like this one before stopping the tests:
