Files not deleted on windows in MappedBufferManager

Question

We are seeing a problem where the nio file-based scheme does not delete the mapped temporary files once they are inactive. This is related to the link below; however, this is not just a problem when the process exits.
Re: nio file manager does not clean up page files on Windows
Given this caching scheme:
<caching-schemes>
     <paged-external-scheme>
     <scheme-name>nio-scheme</scheme-name>
<page-limit>5</page-limit>
          <nio-file-manager>
               <initial-size>8m</initial-size>
               <maximum-size>64m</maximum-size>
<directory>c:/temp/nio/</directory>
          </nio-file-manager>
     <page-duration>10s</page-duration>
<high-units>20000</high-units>
     <expiry-delay>20h</expiry-delay>
          </paged-external-scheme>
</caching-schemes>
The old files are not deleted once we cross the page limit boundary. So the directory will grow indefinitely large as the old files are not removed. We get this error:
MappedBufferManager: failed to remove <path to file>
Note, I added a note to the original posting, but was not sure if it was received since that post was so old. Lastly, this problem appears to be windows-only since the code works as expected on a linux distro using a sun jdk.
We are using JDK 5.0 (build 1.5.0_15-b04) and Coherence 3.2.

Answer 1

I had similar problems. I could always mount the directory but couldn't see any of the files. I finally tracked the problem down to the user name I was using to login from the Mac being in a different XP security group than I had assumed. Once I changed the group membership, it worked as it should.
The solution took awhile to find because my XP laptop is also used on my work LAN and therefore uses "professional" sharing not "simple" sharing. Professional sharing is much more complicated to troubleshoot. You have professional sharing on your XP machine if you see a "permissions" button on the share tab when you click properties on the file/directory.
Here a two good links that might help.
If you have professional sharing:

If you have simple sharing:

Good luck. My apologies if this is too basic for you but I've been working with computers since the early 1970's and still find networking a pain to configure.
