We have a two-server FOG, currently serving 151 sessions, all uttsc in kiosk mode.
Sometime last week(?), we started to see sessions slipping into "DI" state and sticking, and I haven't been able to figure out why. We thought we were running out of licenses for our TS servers, and we do have more traffic there than just our Sun Ray stuff, but after adding a hundred CALs earlier today, the problem didn't appear to diminish. If I kill the sessions marked "DI", they gradually come back, but others go into disconnected state. It seems like we top out between 60 and 64 sessions per server, for a total of just over 120, with the remaining sessions going DI. As far as I can tell, there's no pattern to which DTU's get sick and which ones work. I don't think it's a user account exhaustion issue; we have 200 utku* users configured on each FOG member. On the Windows side, our servers are busy, but not *that* busy. The Windows crew has so far been unable to find any cause for the trouble in their area. I don't find anything in /var/opt/SUNWut/messages that looks related. The only errors look like this: Sep 17 18:04:02 blackstone Sun Ray Connector proxy:[27847]: [ID 855542 user.error] Child closed socket prematurely, session shutdow ...and we get quite a few of those, but they don't seem to coincide with sessions going into DI state. Maybe they're related, maybe not, I can't tell. If I fire up a Sun Ray soft client, I can't duplicate the problem. I've tried connecting to a test Sun Ray server for a JDS session and running uttsc from a terminal there; I've also tried connecting the soft client directly to the FOG where we're having trouble. In both cases, after a few dozen tries, I've gotten a successful uttsc connection every time. Any clues on where to look next?
