25.01 update 6, brand new/reset instance (cleared mongo dir and did --reset-all.)
Once UI came up with page to reset admin password, I got an error that was temporary (reloaded UI page and was then able to log in.)
I added new phones, checking the box to "create another phone after this one" and added two more. On the last phone, I unchecked the box. Saved. Got the red "internal error" message. Couldn't get back into UI (would get the login screen, log in, but then immediately the internal error message.)
I restarted the services (both restart and a full reboot.) Now getting a 503 service unavailable when trying to open the UI (no login window.)
Reviewing sipxconfig.log, I see two java faults:
"2026-06-22T16:40:01.402000Z":382:JAVA:DEBUG:sip-obs.jtdavies.internal:main:00000000:SQL:"select g1_0.phone_id,g1_1.group_id,g1_1.branch_id,g1_1.description,

2026-06-22 09:40:01.403:ERROR:osss.IndexManagerImpl:main: Error during indexing
java.lang.IllegalStateException: Model ID not set
(Is this related to recent patch for "Fixed indexing issues"?)
And then I see:
2026-06-22 09:40:01.515:WARN :oeje10w.WebAppContext:main: Failed startup of context oeje10w.WebAppContext@6778aea6{sipXconfig-web,/sipxconfig,b=file:///var/sipxdata/tmp/sipxconfig/webapp/,a=AVAILABLE,h=oeje10s.SessionHandler@7ff35a3f{STARTED}}{/usr/share/java/sipXecs/sipXconfig/sipxconfig.war}
org.hibernate.AssertionFailure: collection owner not associated with session: org.sipfoundry.sipxconfig.phone.Phone.lines
Any thoughts?
