PPPoE Suricata log flodding

[iam]

Hi,

yesterday I've updated to 19.7.0. Now there are a lot of messages in the Suricata log:

Code Select Expand

suricata: [100294] <Error> -- [ERRCODE: SC_ERR_NETMAP_READ(264)] - Error reading data from iface 'pppoe0': (55u) No buffer space available

Cheers,

Hello,

I am using version OPNsense 19.7.5_5-amd64 and I am seeing the same behavior as you, lots of messages like that:

Hello,

suricata[27960]: [100285] <Error> -- [ERRCODE: SC_ERR_NETMAP_READ(264)] - Error reading data from iface 'pppoe0': (55u) No buffer space available

Any help would be appreciated

It also happens to me on regular basis on three 19.7 instances. When this occurs, internet access, webui and ssh access can't be done.

Were any of you able to find a solution to this issue?
