  • After nexus3 has been running for a few days, the docker proxy repositories start timing out. We have nginx in front of nexus3 and see the following message: {code} $ docker pull docker.englishtown.com/eflabs/kafka:0.9.0.1 Pulling repository docker.englishtown.com/eflabs/kafka Error: Status 504 trying to pull repository eflabs/kafka: "<html>\r\n<head><title>504 Gateway Time-out</title></head>\r\n<body bgcolor=\"white\">\r\n<center><h1>504 Gateway Time-out</h1></center>\r\n<hr><center>nginx/1.4.6 (Ubuntu)</center>\r\n</body>\r\n</html>\r\n" {code} Looking at the nexus log file there is a timeout trying to get a connection from the pool. I would guess at some point connections are not being returned to the pool: {code} 2016-04-20 12:18:50,798-0400 WARN [qtp1912742844-9246] docker-reader
