2.4.1
Since Zabbix 2.4 some availability data from proxy are incorrect:
58:20141019:165348.354 obtained data from proxy "test": {"data":[{"hostid":10291,"error":"Received empty response from Zabbix Agent at [12345678901234567890123]. Assuming that agent dropped connection because of access"}]}
The length of error is 128 characters, it cause errors like:
58:20141019:165348.355 invalid host availability data
and sometimes when Zabbix receives availability data about a few hosts:
45:20141018:183223.008 invalid host availability data
45:20141018:183223.009 [Z3005] query failed: [0] PGRES_FATAL_ERROR:ERROR: syntax error at end of input
LINE 2: update hosts set
^
[update hosts set error='Get value from agent failed: ZBX_TCP_READ() failed: [4] Interrupted system call' where hostid=10234;
update hosts set ]
