I noticed once an error in the logs /var/log/syslog:
asterisk[1324]: rc_avpair_new: unknown attribute 1490026597
asterisk[1324]: message repeated 3 times: [ rc_avpair_new: unknown attribute 1490026597]
Since on this server, Asterisk was configured so that all modules were loaded, and in the /etc/asterisk/modules.conf file a list of modules that should not be loaded was indicated and in my case CDR reports were used, but there was no freeRadius server, therefore to solve the error, I turned off the cdr_radius.so module, for this I indicated in the /etc/asterisk/modules.conf file (after autoload=yes):
noload => cdr_radius.so
Also, in order not to restart Asterisk and unload the module, I connected to it:
asterisk -rvv
And unloaded with the following command:
module unload cdr_radius.so
exit

Oh my god, thank you!
Saved me from going totally insane with my asterisk and this error
