How does one find out what breaks a pipe? The situation in question is nnptd running on a Decstation 2100 (Ultrix 4.1). The first log message refers to a connection where localhost is engaged in an <IHAVE> dialogue with its server (a VMS machine, running ANU-NEWS 6-03, Multinet). Unfortunately, this means that the site which feeds me has to repeatedly re-connect until all items have been processed. The second message refers to a readnews session from a client (a VMS machine, running ANU-NEWS 6-01, CMU-TCP). 04:18:49 localhost: 10238 nntpd: xvax.ucs.unimelb.edu.au disconnect: Broken pipe 12:57:13 localhost: 12395 nntpd: lust1.latrobe.edu.au disconnect: Broken pipe I have run nntp with full logging, but get no more info than the "disconnect: Broken pipe" message. At first I thought it might be a resource problem on the Ultrix side, but increasing the no of user processes (150) has not helped. The only other thing of interest is that no broken pipes are logged from any of our Unix client machines (RISC/os 4.52, AUX, AIX) which run either rrn or xrn. I know this would seem to point a finger at ANU-NEWS, however, the VMS site which feeds me gets a a message indicating it is the Ultrix machine which is at fault: %MAIL-E-LOGLINK, error creating network link to nude LU -SYSTEM-F-LINKEXIT, network partner exited Any help would be appreciated. Since I have cross-posted to so many groups, please email and I will summarise responses (and -hopefully- the answer!). ----------------------- Vicki Jordan La Trobe University Bundoora AUstralia 3083 ccvj@lure.latrobe.edu.au
