Connection leak with hot reload after #5 fix #8
Comments

Hi, how many is |
|
At least 50 times (manually like described above + each time I'm using play.api.test.WithApplication, it seems to reallocate a couchbase connection). |
|
Yes the withApplication will also create a connection for each bucket referenced in your Why don't you use |
|
Ok I have tried with |
|
Are you sure you're using the last snapshot ? |
|
Yes, I have use play update / sbt update to make sure and define |
|
Do you know if tests are launched sequentially or in parallel ? |
|
I have tried with these parameter in Play (2.2.2) + add Maybe it's related to this old issue in Play playframework/playframework#849 |
|
I'm experiencing these core dumps as well while developing with |
|
Hi, does it happen frequently ? |
|
Usually between two and five. |
|
That's low :( Couchbase version ? |
|
I'm running 2.5.1-1083-rel |
|
I'll try to fix that as soon as possible guys |
|
Hey guys, I've just pushed a new SNAPSHOT. Can you try it please ? |

Unfortunately no, after a few compile+reload in ~run mode, I still get: play.api.UnexpectedException: Unexpected exception[ConfigurationException: Configuration for bucket "xxx" was not found in server list ([http://127.0.0.1:8091/pools]).]

Are you sure bucket "xxx" exists ? Because here, it's a pure Couchbase exception saying that bucket "xxx" isn't present on your |

Okay, I just can't reproduce the issue on my machine. Is it possible to create a small application to reproduce the issue so I can try to reproduce it ? |
|
Since I have no idea what causes the issue, it will be a little difficult to build a project that safely reproduces the error. I'll see what I can do. |

Now I'm getting java core dump from hot reload too: It happens after 4-5 code modifications |
|
That's just weird. I tried with a 2.2 and 2.5 server on a sample app with Can you both describe your env. (JVM, Couchbase server, project structure, etc ...) ? Maybe you can try to provide a virtual machine with your env. and app so I can try it myself and debug it. |
Hello,
Now, in my tests suite, I often have this kind of java core dump:
I'm launching tests where I'm not reusing the same connection to Couchbase each time (meaning lots of val driver = ReactiveCouchbaseDriver() and then driver.shutdown() at the end). Am I doing something wrong ?
For the hot reload, after several code modification in my application, I have the following now:
