Some more information on my problem. As I mentioned before I couldn't find anything in the various system logs on the local machine that would correlate a 3am event. I'd also moved the one 3am local job to 2am and that didn't move the problem time. Earlier this week I remembered that 4D Backup runs in the middle of the night. I checked, and yes it is running at 3am. I rescheduled the backup to 5am and now the client hang problem starts at 5am. This is a vanilla backup configured from the server. These backups run quick. I ran one manually during the day and it did not crash the client. We've also never had this problem for as long as I can remember (4D at this site since 95). I ran diagnostics on the server to check the datafile, indexes, etc. No problems reported.
My remote web app monitor sent email that the 4D web client didn't respond with an expected web request at 5:02. Since it only checks every 3 minutes this means the actual problem could have started a few minutes earlier. The unresponsive 4D Remote has crashed each morning the last 3 mornings between 5:10 and 5:13. Therefore it is hung for a few minutes before it crashes. Normally local scripts would reboot it, but they aren't working. So I have 2 problems: 1. 4D Backup is (possibly, but likely) causing a connected client to hang then crash. Has anybody seen this happen? Is there a fix? 2. Scripts to reboot hung or not running 4D that have worked for years no longer do during this time. Again, if I'm logged in remotely via Screen Sharing I can run these scripts fine. I can even run them via SSH and they are fine. For the hung script I will modify to use kill -9 though even though killall works when I test. Using kill -9 may at least allow me to reboot a 5am hang, but I'd really like for the system to not hang at all.
