Does anyone know of a way to trace system calls made by UV as a non-root user? Here's the problem we have: UV on RH ES 5.1 joined to an W2K3 native mode AD domain. We have an AD issue that causes UV to either fail to execute, or die before the user can enter the environment. This doesn't happen to all users, and appears to be random, but affects more users over time. Usually a user can get into UV eventually after repeated attempts. Once they're logged in, everything's fine. --- Update - turns out this is not an AD issue after all (at least not directly, anyway), it's an issue with specific /dev/pts/... terminal device files. I wasn't seeing it with non-AD UOJ connections because they don't use a tty device. Once I realized it only affected a specific tty device, I was able to reproduce it with any login, including root. I noticed that 2 UV sessions were showing in PORT.STATUS with ? as their PID and a blank tty device. "uvlictool clean_lic -a" got back 2 seats. I restarted UV after that, and now the problem's gone. Unfortunately I didn't think to try to reproduce the problem before restarting, so I'm not sure if cleaning up the licencing alone fixed it. Anyone know what might suddenly cause UV tty sessions to hang in an ambiguous state on exit?
