[jira] Commented: (DERBY-3108) Iteratively creating and closing
client connection yields java.net.BindException: Address already in use:
connect after many connections
[ https://issues.apache.org/jira/browse/DERBY-3108?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12532706 ]
Kathey Marsden commented on DERBY-3108:
---------------------------------------
Putting a Thread.sleep(100); after conn.close() seems to allow the program to proceed normally. The memory usage does seem to stabilize as well.

> Key: DERBY-3108
> URL: https://issues.apache.org/jira/browse/DERBY-3108
> Project: Derby
> Issue Type: Bug
> Components: Network Client, Network Server
> Affects Versions: 10.4.0.0
> Reporter: Kathey Marsden
> Attachments: ConnLoop.java
>
>
> The attached program ConnLoop just creates client connections, uses them and then closes them. After about 3000 connections I get the following error. Also the memory usage seems to be increasing rapidly. This may be the cause of DERBY-2344.
