After switch reload all RADIUS server marked dead

[LenarFA]

Hello, looking help for this issue - after the switch reloads, all RADIUS servers are marked as dead for the duration of the dead time criterion (15 min.). IOS Version is 15.2(2)E10. Configuration of RADIUS server are similar to this:

aaa group server radius RADIUS_GROUP
server name ISE_NAME
!
radius server ISE_NAME
address ipv4 x.x.x.x auth-port 1812 acct-port 1813
automate-tester username RADIUS-TEST ignore-acct-port probe-on
key RADIUS_KEY
radius-server dead-criteria time 10 tries 3
radius-server deadtime 15

If i, remove string "automate-tester username RADIUS-TEST ignore-acct-port probe-on" everything works as it should.

If during this dead time i try send test probes via "test aaa group RADIUS_GROUP RADIUS-TEST PASSWORD legacy" nothing happens, no response and the server is marked alive after 15 minutes.
