DescriptionThe WMS Cache Proxy plug-in could not cache %1 to the cache directory. %2
Event InformationAccording to Microsoft :
Cause :
The cache directory on the cache/proxy server is full
To determine whether the cache directory is full:
  1. On the Windows Media server, open Windows Media Services. To open Windows Media Services, click Start, point to Administrative Tools, and then click Windows Media Services.
  2. In the console tree, click the Windows Media server for which you are caching content files.
  3. In the details pane, click the Properties tab.
  4. In Category, click Cache/Proxy Management.
  5. In Plug-in, right-click WMS Cache Proxy, and then click Properties.
  6. In the WMS Cache Proxy Properties dialog box, on the Cache tab, note the cache directory path value in Cache Directory Path. The default value is %systemdrive%\WMSCache.
  7. In the Cache Settings area, note the values for the following options that specify how much space is available for cached file storage in the cache folder:
    • Limit Disk Quota (MB). The amount of space in the cache folder for storing on-demand files.
    • Limit Archive Quota per Stream (MB). The amount of space available in the cache folder for storing a single on-demand file that is created from a live stream by the Play While Archiving feature.
  8. In Windows Explorer, open the cache folder, and then determine how much space is consumed by the cached files.
  9. If the total amount of disk space consumed by the files in cache folder is nearing either of the specified quota limits, see the section titled "Make disk space available for cache file storage."
Resolution :
Make disk space available for cache file storage
There are several methods available to you for making additional storage space available for cached files on the cache/proxy server. Possible resolutions include:
  • Change the disk space storage limit for the cache directory.
  • Remove cached files from the cache directory.
  • Change the cache directory to another location that has sufficient disk space.
Change the disk space storage limit for the cache directory
To change the disk space storage limit for the cache directory:
  1. On the Windows Media server, open Windows Media Services. To open Windows Media Services, click Start, point to Administrative Tools, and then click Windows Media Services.
  2. In the console tree, click the Windows Media server for which you are caching content files.
  3. In the details pane, click the Properties tab.
  4. In Category, click Cache/Proxy Management.
  5. In Plug-in, right-click WMS Cache Proxy, and then click Properties.
  6. In the WMS Cache Proxy Properties dialog box, on the Cache tab, in Cache Settings, use one of the following procedures:
    • If you are storing on-demand content files in the cache directory, select the Limit Disk Quota (MB) check box and then specify a higher capacity value for storing cached files.
    • If you are storing a single on-demand file that is created from a live stream by the Play While Archiving feature in the cache directory, select the Limit Archive Quota per Stream (MB) check box and then specify a higher capacity value for storing the cached file.
Remove files from the cache directory
To remove files from the cache directory:
  1. On the Windows Media server, open Windows Media Services. To open Windows Media Services, click Start, point to Administrative Tools, and then click Windows Media Services.
  2. In the console tree, click the Windows Media server for which you are caching content files.
  3. In the details pane, click the Properties tab.
  4. In Category, click Cache/Proxy Management.
  5. In Plug-in, right-click WMS Cache Proxy, and then click Properties.
  6. In the WMS Cache Proxy Properties dialog box, use one of the following procedures:
    • On the Cache tab, click Clear Cache to remove all files stored in the cache directory.
    • On the Query tab, search for files in the cache directory to remove, and then click Delete to remove the files from the results list.
Note : Cached content actively being streamed by clients is marked for deletion and is deleted when the last user session ends. If another client requests cached content that has been marked for deletion or has been deleted, the cache/proxy server will download another copy of the content from the origin server to fulfill the request.
Change the cache directory
To change the cache directory:
  1. On the Windows Media server, open Windows Media Services. To open Windows Media Services, click Start, point to Administrative Tools, and then click Windows Media Services.
  2. In the console tree, click the Windows Media server for which you are caching content files.
  3. In the details pane, click the Properties tab.
  4. In Category, click Cache/Proxy Management.
  5. In Plug-in, right-click WMS Cache Proxy, and then click Properties.
  6. In the WMS Cache Proxy Properties dialog box, on the Cache tab, in Cache Settings, click Browse to select another cache directory.
Cause :
The origin server is either not available or too busy to process the cache download request
To determine origin server availability:
  1. Use the Ping command to test the local area network (LAN) connection to the origin server.
  2. If you can connect to the origin server, diagnose potential bandwidth bottleneck issues on the network.
Resolution :
Optimize streaming media network availabilityIf the cache/proxy server cannot connect to the origin server on the network, resolve any problems with the network adapter.If the network is functioning normally, investigate and resolve potential bandwidth bottleneck issues on the network.If the network is tuned correctly, try restricting the cache download caching speed on the cache/proxy server to the available bandwidth.
To restrict the cache download caching speed to the available bandwidth:
  1. On the Windows Media cache/proxy server, open Windows Media Services. To open Windows Media Services, click Start, point to Administrative Tools, and then click Windows Media Services.
  2. In the console tree, click the Windows Media server for which you want to cache content.
  3. In the details pane, click the Properties tab.
  4. In Category, click Cache/Proxy Management.
  5. In Plug-in, right-click WMS Cache Proxy, and then click Properties.
  6. In the WMS Cache Proxy Properties dialog box, on the Cache tab, in Caching Speed, select the Maximum Available Bandwidth option to allow caching of content from the origin server as fast as the network will allow.
  7. Click OK to save the changes.
Note : If the network is operating near maximum capacity, the cache download speed may still be slow. A streaming media network that has been correctly planned and configured will improve response time, data throughput, content availability, and reduce the data error rate.
Verify :
To verify that cache/proxy servers on your network can cache content files from the origin server, prestuff the cache directory on the cache/proxy servers with one or more content files from the origin server. Prestuffing content means that you are caching the content on the cache/proxy servers before it is requested by clients. It is a good way to confirm that cache/proxy servers on your network can communicate with the origin server.
