I am running a TCP to DECnet gateway using Ultrix 2.2-1 on a Microvax II. It has been working very well until just recently. Now people attempting to use the gateway from the SPAN side are getting messages about insufficient system resources, such as %COPY-E-OPENIN, error opening 9580"host!user password"::"file" as input -RMS-E-ACC, ACP file access failed -SYSTEM-F-REMRSRC, insufficient system resources at remote node The only messages on the machine itself are syslog entries of the form "dnet_spawner: process exited". Not very helpful. Attempted mailing through the gateway is also failing with an apparently similar problem about mail11 not being able to create a socket. There have been *NO* changes made to any of the software on this machine since it was brought up a year ago. It is possible that usage patterns have changed, but I don't know how to determine this. At any rate, does anyone know if there is anything I can do to increase "system resources", or have any idea why this problem would have suddenly come up? If it matters, I am a UNIX expert and fairly knowledgeable about TCP, but know almost nothing about VMS or DECnet. --Greg

If that's not the problem, it could be you are running out of mbuf's since in V2.2 the mbuf pool was a fixed size (ie. the pool itself didn't grow). There are some configuration file parameters that you can change to increase this (sorry, I don't know what they are). -- /--------------------------------------------------------------\ |Jeff Michaud michaud@decwrl.dec.com michaud@decvax.dec.com| |DECnet-ULTRIX #include <standard/disclaimer.h> | \--------------------------------------------------------------/
