These pauses are frustrating. What could be causing them? >Thanks for considering the problem One person has stated that they have seen this behavior feeding news from a FreeBSD box to a Solaris box and suspects unoff3. (May I suggest running innxmit with -d and seeing if any useful info is provided?) Another person has suggested that when the pauses occur, the article being transferred is large, accounting for the pause, or that connectivity to the other end has been lost. First, connectivity is still present. Other traffic to/from the site goes fine. Second, It does, in fact, appear that the article at the time of the pause is large, anywhere from .5 to 1.5 megabytes. However. being *extremely* pessimistic, this should take no more than 2 minutes to transfer over our connection. The feeding site is very close to us, (we share a common router). Furthermore, there doesn't appear to be any active transfer of data during the pause. Is there any further method of diagnosing the problem or does anyone know what may be causing this? ---- Dave E Martin Main groups and alt, wrapped in 2,500,000 sectors P11 XXIII KB7VBD of spinning cylinders, all alone on the disk.
