Error 3091: Index is busy: most likely, another application has opened the index with the ZyINDEX option.

SYMPTOMS

Error message: Error 3091: Index is busy: most likely, another application has opened the index with the ZyINDEX option.

Or:

Error message: error 3091: Index is busy while opening an index.

CAUSE

This error message can have three causes:

1. If you are using Windows 95/98 and you are not logged on to a PC as a user with an active user profile. 
2. The values for LockName, LockUser or LockPid in the settings.txt have invalid data in them. This might have happened during illegal shutdown of pc while running ZyINDEX. 
3. The logged on user does not have sufficient rights on the index folders.

RESOLUTION

1. Always log on with usersname and password. This is important on a standalone pc where it might be possible to log on without a username or password. Win 95/98 and ME can operate with no log on but ZyIMAGE requires an active user profile. For Windows 98 press the Escape-key when starting the PC.
2. Delete the contents of the lockname, lockuser, lockpid in the settings.txt of the index returning the 3091 error while opening. Set the values to:
   [General]
   LockName=
   LockUser=
   LockPid=0
   If removing the entries does not solve the problem. Reboot the machine. Erase the index and rebuild again. 
3. Ensure that the logged on user has full control on the index folders.
   For example, if an installation sets the index root directory to the Zylab data directory of a network drive like 'F:' then the logged-on user must have full control of the 'F:\zylab data\indexes' folder.
