<span style="font-size: 12pt; color: black;">Hi All,</span></p>

<span style="font-size: 12pt; color: black;">When I got iocsoftinj3 running 3.15.6 on RHEL9 (opsbat9), it entered a continual reboot cycle. This seems to be related to the system database 7.1. Sue has reported having the same problem. The ioc runs fine without
system. As a test I also built 7.0 against 3.15 on RHEL9, and the ioc runs fine with this version. Does anyone know what causes this?</span></p>

<span style="font-size: 12pt; color: black;">I had been building on my local machine, which is 9.1. I rebuilt, relinked and restarted, and now it's booting, but immediately crashing, which is progress I guess! Maybe I just hadn't run makelynx or something.
I'll try 3.15.9. Thanks again.</span></p>
