Empty data after some idle time (about 30 min)

[alexk24]

CentOS Linux release 7.3.1611 (Core) + EPEL
java-1.7.0-openjdk-1.7.0.131-2.6.9.0.el7_3.x86_64
vmbix installed from vmbix-2.6.0.157-1.x86_64.rpm

After some idle time (about 30 min) working it start return empty data:
#zabbix_get -s 127.0.0.1 -k "vmbix[esx.discovery,*]"
{"data":[]}
#zabbix_get -s 127.0.0.1 -k "vmbix[cluster.discovery]"
{"data":[]}

After restart it again working. Logs seems clean.
