Hello gentlemen,

I have a QLogic FC card in a FreeBSD, connected to a CX300 storage
which sometimes looses connection with no aparent reason. If someone
had lived a similar problem or know of something that would help
diagnose the cause, I would like to hear.

When the problem happens all I get in the logs is:

and later, FreeBSD freezes (sometimes it panics).

It is not very often that it happens, and it is under completly random
circunstances (sometimes high load, sometimes the lowest load, on
different hours, etc).
