The log of zabbix_server shows the error for some hosts:

10819:20190103:205950.114 error reason for "<hostname>:vfs.fs.size[/var,used]" changed: Value 7570672582656.000000 is too small or too large.
 
   And even though I disable the items below, the errors still appear in the log:

 Template_Linux: Free disk space on /var |  vfs.fs.size[/var,free]
 Template_Linux: Free disk space on /var in % | Triggers 1 | vfs.fs.size[/var,pfree]
 
 How do I correct these errors?
