The most recent beta release has a few problems, most of which are not worth posting (we'll fix them and do another release in a week or two). But, one is causing quite a few problems. The symptom is that "site_getview" hangs when called in the most recent site to have started up at any given point in an ISIS run. It works fine on machines that have been up for a while, and unhangs itself the next time you restart some other machine. Here is a simple fix. Edit clib/cl_sview.c and change the first few lines as follows: sview * site_getview() { register sview *sv = act_blocked? &isis_svmutex: &isis_sv; if(sv_known == 0) { if(SITE_NO(sv->sv_slist[my_site_no]) == RECOVERY_INCARN) t_wait_l(&wants_view, "site-getview: waiting for first view"); sv_known = 1; } return(sv); } Hope that no other really annoying problems turn up. As for the minor ones... well, if you report them, we'll be more than happy to keep fixing them. By the way, let me reiterate that this is a BETA release. By definition, that means that we expect bugs to crop up and are hard at work fixing them. ISIS V1.0 and V1.1 were extremely solid by the time we declared them to be in a "general" release, but both versions went through a similar shakeout period. So, if all this worries you, please bear with us -- it's quite normal.
