Possible socket leaking in CallbackServer
-----------------------------------------
Key: CB-107
URL: https://issues.apache.org/jira/browse/CB-107
Project: Apache Callback
Issue Type: Bug
Components: Android
Affects Versions: 1.2.0
Reporter: Simon MacDonald
Priority: Critical
I think we may be leaking a socket in CallbackServer. On line 216 of the
CallbackServer we create a new Socket but I can't see anywhere in
CallbackServer where the Socket is closed. Over time this could cause the
problem described below. The user is probably running into it much sooner than
usual as he's making a file write every second.
Here is the original bug report from the Google Groups:
I'm trying to write approx every second to a file. This for writing a
geolocation to this file.
So I make a filewriter when I start tracking, then start a
watchposition en in the successfunction I write to this file.
In my first tests everything went well, but with some more intensive
testing we found out that after more than 900 points (or
filewritervar.write() callings) the app fails. In the logcat the next
error is vissible:
[code]

[/code]
I looked in the FileUtils.java file and the filestream is everytime
correctly closed, so I dont see the problem.
