Hello,

I am receiving a strange segault in dmesg every few hours... and then nginx orphans those connections, so after about a day there are 2000-3000 connections that are just "waiting".

This isn't that bad, as the server has received over 1,228,503 connections since a restart this morning, but still those orphaned connections pile up, and I have to restart nginx to clear them.

Here is what I am receiving:

I know that libkrb5 is for kerberos... I don't think I am even using that in my configuration. No DAV support, etc... So I don't understand exactly why nginx is faulting.

Please let me know what additional information I can send that would be helpful.
