Occasionally we are seeing the go-test-api job timeout at 10 minutes. Looking at the stack trace I saw the following: 1. Lots of tests blocked on server.Stop in NewTestServerConfigT. This suggests that SIGINT is being sent to the server, but the server is not properly shutting down. 2. Over 20k goroutines that look like this: goroutine 16355 [select, 8 minutes]: net/http.(*persistConn).readLoop(0xc004270240) /usr/local/go/src/net/http/transport.go:2099 +0x99e created by net/http.(*Transport).dialConn /usr/local/go/src/net/http/transport.go:1647 +0xc56 Issue 1 seems to be the main problem, but debugging that directly is not possible because our buffered logs do not get sent when the tests timeout. To mitigate this problem I've added a timeout to the cmd.Wait() to force kill the process and return an error. Unfortunately because we retry this operation, we still may not see the cause because the next attempt will likely pass. I'm tempted to remove the retry around NewTestServerConfigT. Issue 2 seems to be caused by not closing the response body. Since the request is performed many times in a loop, many goroutines are created and are not closed until the response body is closed. |

Consul
- Website: https://www.consul.io
- Tutorials: https://learn.hashicorp.com
- Forum: Discuss
Consul is a distributed, highly available, and data center aware solution to connect and configure applications across dynamic, distributed infrastructure.
Consul provides several key features:
-
Multi-Datacenter - Consul is built to be datacenter aware, and can support any number of regions without complex configuration.
-
Service Mesh/Service Segmentation - Consul Connect enables secure service-to-service communication with automatic TLS encryption and identity-based authorization. Applications can use sidecar proxies in a service mesh configuration to establish TLS connections for inbound and outbound connections without being aware of Connect at all.
-
Service Discovery - Consul makes it simple for services to register themselves and to discover other services via a DNS or HTTP interface. External services such as SaaS providers can be registered as well.
-
Health Checking - Health Checking enables Consul to quickly alert operators about any issues in a cluster. The integration with service discovery prevents routing traffic to unhealthy hosts and enables service level circuit breakers.
-
Key/Value Storage - A flexible key/value store enables storing dynamic configuration, feature flagging, coordination, leader election and more. The simple HTTP API makes it easy to use anywhere.
Consul runs on Linux, Mac OS X, FreeBSD, Solaris, and Windows. A commercial version called Consul Enterprise is also available.
Please note: We take Consul's security and our users' trust very seriously. If you believe you have found a security issue in Consul, please responsibly disclose by contacting us at security@hashicorp.com.
