Steps to reproduce:

1. Using the Debian 4.4 Zabbix APT repository (http://repo.zabbix.com/zabbix/4.4/debian jessie main), I've been running 4.4 since the day that it was released
2. After upgrading to 4.4.2 recently, the agent is crashing a few minutes after starting and will not stay running

Result:

See attached log file (zabbix_agentd.log)

Expected:

It should not crash. 

Notes:

1. I do not use LDAP any where
2. All of my other agents are fine and proxy are fine, but none are Debian 8.11
3. This agent is not behind my Zabbix proxy
4. This agent is using TLS pre-shared key (PSK) -  so are the rest of my Zabbix agents/proxy
