[Zope] [Q] Error - StorageSystemError

[YOON, Joo-Yung]

I installed/deinstalled zope-2.3.2 several times everytime I
get this error message.

File /usr/local/zope/2-3-2/lib/python/Zope/__init__.py, line 110, in ?
File /usr/local/zope/2-3-2/lib/python/ZODB/FileStorage.py, line 264, in __init__
File /usr/local/zope/2-3-2/lib/python/ZODB/lock_file.py, line 101, in lock_file
StorageSystemError: Could not lock the database file. There must be 
another process that has opened the file.
<p>

I could not login to the server by telnet.  And then boot the system
as "linux single", and deleted zope, and re-boot, and reinstall it.

I really do not know what to do.  Please help me out.

Thanks.
