Linux 5.10.0-15-amd64 #1 SMP Debian 5.10.120-1 (2022-06-09) x86_64 GNU/Linux
zabbix-server-mysql/unknown,now 1:4.0.41-1+debian11 amd64 [installed]
Fping: Version 4.4
Steps to reproduce:
- Create ICMP simple check which results in TTL exceed message
Result:
If fping returns message "ICMP Time Exceeded from..." for one of tested hosts of pinger process, then this and all others tested hosts are marked as "not supported".

Fping process sample output:

Expected:
Host 109.236.117.142 should have 100% ping loss. Other hosts measured by the same pinger process must not be affected.
