Log message: Error watching...no space left on device
Reason
PowerFolder Server uses the iNotify kernel API on Linux systems to watch for changes in the file system. If there are a lot of folders with deep directory structures and many files, the system kernel may block requests by PowerFolder Server to scan for changes, therefore it is necessary to raise the limits on larger installations.
Solution
Raise the file limits as described in our Installing on Linux Guide. Afterwards please restart the service.
