Title: PPPoE Suricata log flodding
Post by: iam on July 18, 2019, 06:05:21 pm

Hi,

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

Code: [Select]

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

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.
