Now there are just brief pauses every 3-5 loops (instead of hangs?). So if someone tests this in 9.0-STABLE and finds that it doesn't hang, this PR should be closed. -- -------------------------------------------- Peter Maloney Brockmann Consult Max-Planck-Str. 2 21502 Geesthacht Germany Tel: +49 4152 889 300 Fax: +49 4152 889 333 E-mail: peter.maloney@brockmann-consult.de Internet: http://www.brockmann-consult.de --------------------------------------------
