Zabbix - Utilization of housekeeper processes over 75%

I'm monitoring about 1300 hosts on Zabbix. After I defined bulk templates for all hosts, I got the "Utilization of housekeeper processes over 75%" alarm, but it was not resolved for about 20 hours. I did not define a housekeeper in my server settings. How can I resolve this alarm and what is the effect? Using postgresql.

Server config;

StartPollers=50
StartPollersUnreachable=50
StartPingers=50
StartDiscoverers=50
StartHTTPPollers=50
CacheSize=1024M
HistoryCacheSize=1024M
TrendCacheSize=1024M
ValueCacheSize=1024M
LogSlowQueries=3000
MaxHousekeeperDelete=5000

Postgreqsql config;

max_connections = 1000
shared_buffers = 8GB
effective_cache_size = 24GB
maintenance_work_mem = 2GB
checkpoint_completion_target = 0.9
wal_buffers = 16MB
default_statistics_target = 100
random_page_cost = 1.1
effective_io_concurrency = 200
work_mem = 1048kB
min_wal_size = 1GB
max_wal_size = 4GB
max_worker_processes = 12
max_parallel_workers_per_gather = 4
max_parallel_workers = 12
max_parallel_maintenance_workers = 4​

We fixed this on Zabbix 5.0 by Administration > General > Housekeeping (drop down) and changing all the 365 data storage periods to 183

That changed peak utilisation from 100% to 59% and average utilisation (housekeeping runs again an hour after it finished) from 6.7% to 0.56%

We never looked at history more than two months old so no functionality was lost for us
