Clients loosing Lan connection - KEA - DHCP - No buffer Space available

[Mayo132]

Hey everyone,

last days i recieve some interrupts in my Network.  But at the moment i can not figure out where the problem is located.

Some days ago i got the information about some clients lost the connection to the internet for some time (approx. 20 seconds). After this time, everything is working fine.

Today, the same problem also happened, but this was the first time, i found a strange entry in my KEA log. But until now i can not interpret the error message.

Code: [Select]

2024-06-04T14:03:17 Error kea-dhcp4 ERROR [kea-dhcp4.packets.0x834410400] DHCP4_PACKET_SEND_FAIL [hwtype=1 f4:a8:0d:6e:7f:8a], cid=[01:f4:a8:0d:6e:7f:8a], tid=0xe600623e: failed to send DHCPv4 packet: failed to send DHCPv4 packet: No buffer space available

Maybe someone knows this error ?

Thanks a lot.
