FSRM_E_CACHE_MODULE_ALREADY_EXISTS

FSRM_E_CACHE_MODULE_ALREADY_EXISTS indicates that configuration attempted to add another module of the reserved cache storage-module type. FSRM supports a single cache module responsible for the service property cache.

Do not register third-party modules as cache modules

  • Enumerate existing storage-module definitions and identify the current cache module.
  • Use an in-file or database storage-module type for custom property persistence where appropriate.
  • Remove duplicate or stale registration only after confirming which module owns existing cached values.

The FsrmStorageModuleType_Cache value is reserved for FSRM and is not a general high-performance storage option for plug-ins. Replacing the cache module casually can orphan metadata or change how file moves are handled. Correct the module type in the installer or configuration source instead of repeatedly deleting the active system definition.
