<p>Hello all,</p>
<p><br>
</p>
<p>I'm troubleshooting a very high decoder.invalid count on my sensor; nearly 35%. My kernel drop count is less than 1% and we seem to be generating about the number of alerts that I would expect. I'm not able to find much in the way of documentation that explains
what may lead to a packet being marked as invalid in Suricata. The only thing I've found so far is advice to make sure that the interface MTU and Suricata.yaml MTU settings match (which they do) and ensure that the MTU is large enough for packets being seen
on that interface (it is). I even tried to increase the MTU to 9026 without any difference. Can anyone point me in the direction of other factors that could be at work here?</p>
<p><br>
</p>
<p>Thanks</p>
