Anyone have longer smokes than normal times?

[Trip]

Started noticing this with ribs, took way over 6 hours and still wasn't fall off the bone.  All of my butts and brisket have gone 18 hours or more.

I have checked temps all over my smoker with different probes and the temp seems correct.  Noticed on the video old sarge posted that some people with 3's seem to be experiencing the same long smokes.

Well I finally worked out my issues.  I had a bad probe and a loose wire on the relay that was causing an intermittent issue.  I  noticed it when I smoked a butt and a brisket flat last night and used more probes than normal. 

I was hooking everything up and changing probes around and noticed every time I would plug a probe in the pit temp would do wonky things.  Finally the probe just failed and started reading 300+ degrees when I was messing with it.  Just as I was about to claim success and use other probes, my cat5 connection for my SSR fell out and the pit temp dropped 20-30 degrees.  I put it back in and it went up again.  I started checking into it and it didn't always mess with the pit temp, so when I was doing my temp tests without any meat I was seeing accurate temps when comparing it to other nonheatermeter probes.  I finally sourced it to the negative rail connection on the SSR for the cat5 was loose.  Smoked the flat in about 9 hours and the butt was done just under 12 hours.
