Computer keeps rebooting at startup

Thank you for offering me to help me.

Shall I upload the whole list? Its quite long.

I can in it see any errors in it

Sorry, I misunderstood.... just the lines before the BOOT_TIME.... to see what triggered the reboot.

Ok, how many lines above?

I hope this is not too long:

thank you for looking at it!

Thank you for your suggestion.

The only problem is, I use the Mac only to work with my Drobos.

If the drobos are not connected I would not need the Mac, because my main computer is a PC.

But I will talk to the Drobo and also the CalDigit will see what the suggest.

Ok, I will disconnect them tomorrow.

I have 2 CalDigi cards installed

Update:

this morning I removed all drobos which are connected to the 2 CalDigi cards + an open enclosure which are all USB 3.0 connections. I kept the other Drobo connected which uses iSCSI.

The Mac is now on for about 1 hour and has not rebooted.

In order to pinpoint the trouble, I will then start to connect one at the time and see, when it starts rebooting.

I really appreciate your suggestion, because I was looking into a far different direction. (mostly suspected RAM problems-because sometimes when reboot, the power-on light is flashing and there is no boot-but that happen very seldom). Also, I thought, maybe the high humidity could have created that problem.

I have problems with USB 3.0 ever I bought my Drobos which are USB 3.0.

I bought my first CalDigi card, which always disconnected my Drobos, after that I bought the CalDigi Pro. That is more stable now. But I have 3 more Drobos by now. And the toaster which I need for data transfer to 2.5" and 3.5" drives.

Maybe that causes the problem...... The only other solution I could think of, just use the CalDigi Pro and an AC USB 3.0 hub. What would you suggest? I need the Drobos, because there are all my videos on.... and they getting more! (This is not my private video collection, but 5k videos I am producing.)
