Hi all,
Can I use a shared windows file system to achieve "Shared File System Master
Slave"? I have made some tests, but occasionally some error would occur. I made the
test under 2 instances of activemq-4.2 runing on WinXP. The errors are as follows:

Is this error due to the insufficient support of "exclusive file locks" by
Windows.
The above looks like a bug. I'm guessing you've used a fairly old
snapshot of 4.2, I'd recommend using a recent one from the end of
March 2007 which no longer uses activeio AFAIK.
