I have one history syncer and it cannot rotate export history file, because folder permission decreased by admin (write perm is lost).
I try to terminate zabbix_server normally (SIGTERM to main process), but the child history syncer does not exit on parent's request:
19672:20191015:222556.503 cannot rename export file '/tmp/22/history-history-syncer-1.ndjson': [13] Permission denied: retrying in 10 seconds ... repeated many times .... 19666:20191015:223234.329 Got signal [signal:15(SIGTERM),sender_pid:10497,sender_uid:0,reason:0].

Zabbix 4.4.0 (revision cfac660b25).
The child exited only when I fixed permissions on /tmp/22/ folder that it finally could rotate the export file.
Interesting that in finally rotated file server wrote only one value - dated "2019-10-15 22:25:55". This time stamp is ~ when server started to attempt to rotate the export file.
In the log output the syncer was in Debug level.
