When configured for DEBUG mode, the discovery.log shows the following:

2022-09-20 06:11:36,989 DEBUG [ping-sweep-2] o.o.c.t.RequestTracker: Scheding timeout for request to [ID=JniPingRequestId[addr = /172.20.193.170, ident = 7491, seqNum = 1, tId = 392252],Retries=1,Timeout=2000,Packet-Size=64,Expiration=1663679498989,Callback=org.opennms.netmgt.icmp.LogPrefixPreservingPingResponseCallback@39c1738] in 2000 ms

I believe "Scheding" should be changed to "Scheduling".
