我正在尝试在运行Debian和Python 2.7.1的Web服务器上使用ZODB 3.10.2.似乎每次我尝试从2个不同的进程访问同一个数据库时,我都会遇到一个神秘的异常.我尝试从交互式Python会话访问数据库,一切似乎都正常:

>>> import ZODB
>>> from ZODB.FileStorage import FileStorage
>>> storage = FileStorage("test.db")
>>> 

但后来我尝试了同时运行的另一个会话中的同一系列命令,但它似乎不起作用:

>>> import ZODB
>>> from ZODB.FileStorage import FileStorage
>>> storage = FileStorage("test.db")
    No handlers could be found for logger "zc.lockfile"
