[jira] [Commented] (GEODE-192) ClientServerTransactionCCEDUnitTest.testClientCommitFunction fails intermittently

["Dan Smith (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GEODE-192?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14971840#comment-14971840 ] 

Dan Smith commented on GEODE-192:
---------------------------------

I've tracked this down, and I've made a couple changes to the test to make it reproduce every time.

The issue is that the test only invokes functions to access the data on the server. When it calls  TransactionFunctionService.onTransaction, that method requires the client to already have a connection to the member hosting the transaction. But the earlier function calls may have gone through the other server.

The reason the test passes most of the time is that the PRsingle hop mechanism asynchronously is creating a connection to all of the servers. If that runs in time the test will pass. Disabling single hop and setting min connections to 0 makes the test fail every other time.

> ClientServerTransactionCCEDUnitTest.testClientCommitFunction failed recently on a private build. The only changes on that branch (feature/GEODE-185) had to do with an expiration unit test and some minor expiration changes.
> This failure is intermittent even on that branch.
