Dear LanX, Corion and Anonymous Monk!

Thanks for your suggestions! Here are some results of my tests:

• It is depending on the perl-version ... perl 5.14.2 works without problems
• It really seems to depend on the size of the dump - the result is the same independently if I write directly to the logfile or if I redirect
• Even with dumping the data in a loop (with redirection), the same error occured (there might be a problem that the perl-script writes the data faster than it could be processed ...)

Summary: I "solved" the problem by reducing the amount of debugging-info, and by using a newer perl-version when all data is really needed. Your comments helped me reaching this solution :-) .

Thanks a lot! Rata
