zabbix-proxy stops working after a while, in the log file

the log stops on this record

the data stops coming to zabbix-server

i made a trigger to monitor the work of the zabbix proxy

change(/zabbix.nsc-tech.ru/zabbix[proxy,zabbix-proxy.cde.ruru.lan,lastaccess])=0

zabbix-server constantly receives the latest data from the proxy, this value will be received until zabbix-proxy is restarted

to solve the problem, you need to restart the server, restarting the zabbix-proxy service fails it freezes
