Zabbix 4.2.2 pinger - [12] Cannot allocate memory

[bilbolodz]

I'm pinging about 500 ip addresses from zabbix server (Simple check: icmpping). But for some items I can't get result (no data from ping) In log file I can see:

  1607:20190603:230503.802 /usr/bin/fping -C1 2>&1 </tmp/zabbix_server_1607.pinger;/usr/bin/fping6 -C1 2>&1 </tmp/zabbix_server_1607.pinger;: [12] Cannot allocate memory
  1507:20190603:230504.209 error reason for "ekw:icmpping[,1,,,]" changed: /usr/bin/fping -C1 2>&1 </tmp/zabbix_server_1607.pinger;/usr/bin/fping6 -C1 2>&1 </tmp/zabbix_server_1607.pinger;: [12] Cannot allocate memory

Any ideas what could be wrong and how to fix it?

It looks that's a problem not only with pinger process but also with discovery, I've found in logs:

Failed to execute command "/usr/lib/zabbix/externalscripts/discover_openvpn_vpn1-1.sh": [12] Cannot allocate memory

It's script from discovery. So general question is:

How to check why zabbix server is suffering from "memory allocating problems"?

Solved: I've increased server "physical" memory. Errors gone zabbix checks working.
