Re: Why does my MP2 crash intermittently?

[Foo Ji-Haw]

Hello Nikolay,   You mean you didn't use the ActivePerl distribution? You do this to avoid the OEM licensing issue? I am using the standard ActivePerl 5.8.7, with MP2.0.1 and Apache 2.0.52. I hope this is not the cause of the problem.   "Nikolay Ananiev" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED]... > > Hello, > I had a similar problem with mp2 on windows.
