有时我的 play2 应用程序可以工作，但有时不能。我怀疑它没有在开发模式下释放连接。这是错误：

这是我的配置（我只放了我添加的条目来解决这个问题，但似乎没有帮助）：

db.default.partitionCount=1
db.default.maxConnectionsPerPartition=5
db.default.minConnectionsPerPartition=1
db.default.acquireIncrement=1
db.default.acquireRetryAttempts=1
db.default.acquireRetryDelay=5 seconds

不知道是不是跟cloudbees或者play有关。类似游戏的人说它在游戏 2 （一月）中解决了，但似乎没有..
