Zabbix agent. Cannot obtain a list of filesystems: [0x000005AA] Недостаточно системных ресурсов для завершения операции

I need to monitor disks on Windows hosts. I use template Mounted filesystem discovery. Zabbix Agent 6.0.6 are installed on the hosts.  After that I get error "Cannot obtain a list of filesystems: [0x000005AA] Недостаточно системных ресурсов для завершения операции." I guess it depens on mouted FDD because it work well where hosts without a fdd are located. I can't disconnect the FDD because I need it.

I get the same error using command on the Zabbix server 6.0.4:

zabbix_get -s 192.168.150.10 -k "vfs.fs.discovery" 

How to avoid it?
