Controlling the Maximum Open Volumes for LMSFM (93557)

SUMMARY

On a server with many Macintosh machines connecting to many volumes, an

AFP0033:Request to open too many volumes

error can be generated when the default limit of 40 concurrently mounted volumes is reached.

MORE INFORMATION

An undocumented parameter can be added to the LANMAN.INI file in the [MacFile] section that controls the number of maximum concurrently mounted volumes the MACFILE service can support at once. This parameter, maxvolumesopen, is defaulted at 40. Its range is 0-500. By adding it to the LANMAN.INI file as shown below (and using an appropriate number), you can avoid the above error, and the Macintosh users can mount the necessary volumes.

Example

[MacFile]
maxvolumesopen = ###

  ; There are no mandatory settings for the MacFile service.
