Weird error

[Jacques Le Roux]

Hi,

I got this weirs error somehow and I don't clearly remember when and where. So 
I don't want to create a Jira.
Just asking if someone ever got the same or has an idea about it, else please 
neglect

Note: maybe it was in the context of using a penetration tool. Like sending an abnormally large HTTP header. I noted it but can't clearly remember the 
context.

Thanks

Jacques
