We have recently seen 2 crashes of the server. It writes a _lot_ (at least 10 / second) entries to the event log:
A call from the agent to the server failed, it will be re-tried again after the connection has been re-established.
There was no endpoint listening at net.pipe://localhost/ContinuaCI/IAgentCallbackService that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.
1 / second is enough š

We were not able to reproduce this on our dev machine, but I found that we were not using the latest sqlce assemblies, so updated them, put that build on our build server andā¦ bangā¦ same problem! So my guess is that for some reason Continua CI is picking up the newer version on your machine. Googling the error doesnāt provide any solutions. Still investigating.

Hi Geert
I think we have this solved, at least Iām no longer able to reproduce it. Please try this build (you will need to update your agents). This build has built itself several times and was tested with lots of clients opening the same log view so Iām reasonably confident it fixes the problem, but weāll do more testing tomorrow
Please make sure you have a database backup as this build also includes some schema changes that are not backwards compatible (ie if you have to roll back to an earlier build it will not work with the new schema).

The default agent properties seems to be missing now (no properties).

Yes, both from the installer of the server (just hit yes if you want to install the agent) and a separate download. Even rolling back to a previous version does not seem to work (both agent and server). At first I see the properties (93), then they disappear.

Rebooting the machine solved the issue. I can now view properties with the old agents. Maybe for the new install, you also need a full reboot? We are using Windows Server 2012 R2.

Not sure why, a reboot should not be needed, the installer stops the service before doing anything. But then with wcf anything can happenā¦ sigh!

I manually restarted the services several times. I donāt know how the agent reads its properties, but maybe there might be an issue there? Existing environment variables that no longer exists? Just popping up some ideas which might help you find out the cause.

Iām getting the same error. I need to reboot everytime to resolve this.
The server and agent is on the v1.0.0.2859.

Hi Vincent,
NullReferenceException. Then, after the error, the message: āA call from the agent to the server failed, it will be re-tried again after the connection has been re-established.
There was no endpoint listening at net.pipe://localhost/ContinuaCI/IAgentCallbackService that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.ā shows up on CI Server.
Even restarting the āContinuaCI Agent Serviceā a lot of times, the message continue to shows up. Then, I need to reboot the system.
By the way, even restarting all the Continua CI services, the message shows up.

Hi Lucas
I wasnāt able to reproduce the problem here so itās not possible to say that itās fixed, but I made some changes to the error handling in the area where the error is occurring. Please try this build. Itās been running all day on our server without any errors.
