 Description   

Each Zabbix application process, holds file it was writing last. It can be very problematic when LogFileSize > 1GB. In this case multiple processes of zabbix can hold plenty of deleted files. Which can lead to host malfunctioning because of no free space available.

example of test with 1Mb files:

#lsof | grep deleted

Expected:
Release space of deleted file

Solution could be found using copy and truncate instead of delete and create.
