7.12 (Netscape LiveWire Bundle) vs. Solaris 2.5.1

I apologize if this question has been asked and answered previously (or if this is simply a stupid question), but a client is having major problems with their 7.12 Online installation (it came with LiveWire) and I'm mystified. They installed it under SunOS 4.1.3 on a Sparc 20 with no problems, but then they upgraded the system to 2.5.1. Since then the daemon goes up for around 11 minutes and then conks out with a "Panic - Master Daemon died" sort of message. As a possibly related problem, I'm getting "Network Down" in onmonitor, but I'm thinking that's some sort of .rhosts/.netrc deal (I've dealt with that before). I've reconfigured the shared memory according to the specs and various other suggested values to no avail... I'm ready to give up. Anyone have any ideas? I would be appreciative to no end. sam bailey entropy media sbailey@entropymedia.com ps. I should mention that it's using tlitcp as opposed to ipcshm.
