 In any case it can't be classified as port bug, as you suggested
 in previous letter, unless program has direct access to kernel memory or
 raw disks. I don't believe he run leafnode as root.

 Totally wrong. Problem can be triggered with specific config or specific
 running history. It even can be irreproduceable, if it can be diagnosed.
 If it is reproduceable, it can be diagnosed much easier.

 This is also possible but you haven't *any* real arguments "pro" it.
