-----------------------------------------------------------------
Key: AXIS2-3883
URL: https://issues.apache.org/jira/browse/AXIS2-3883
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Affects Versions: 1.3
Environment: Windows server 2003 (also Windows XP), axis 2.1.3,
Websphere 6.1
Reporter: LEE
Priority: Blocker
We have been regularly experiencing the following problem when trying to call
an axis 2 webservice:

On closer inspection of the server we noticed that there are a great number of
files in the Windows/Temp directory with names such as
C:\WINDOWS\Temp\_axis2\axis21568addressing-1.3.mar,
C:\WINDOWS\Temp\_axis2\axis21574soapmonitor-1.3.mar,
C:\WINDOWS\Temp\_axis2\axis21579rampart-1.3.mar,
C:\WINDOWS\Temp\_axis2\axis21577ping-1.3.mar etc.
The main concern (other than disk space is gradually being taken up) is that
all these files still have open file handles. This is a major problem for us as
each time a call is made to a webservice more of these files eventually
resulting in the application failing due to "too many open files" error.
