I had a project that was crashing every time it got to the end of a loop, and after some detective work the problem seemed to be caused by having the ARC2 plugin turned on. As soon as I turned it off, the problem went away. Hasn't happened in any other project yet but it does worry me a bit. Just wondered if anyone else had seen anything like it. 

I've just recently installed ARC2 on my new PC along with quite a few other plugins. I am now having an issue with sonar crashing whenever I load channel tools into a track and select a preset. I will check on this when i get home.

No issues here

Its been rock solid here.

rock solid here as well.
 
 
 

I had a problem after some seemingly unrelated hardware upgrades after which all projects containing ARC 2 would crash upon loading. Removing the ARC plugin and reinstalling fixed it and I've had no problems since.

Never had an issue...
 

Interesting that you would have this happen at the end of a loop, sharke. Last night I was looping a section and experienced dropouts just before the end of the loop. I thought it was due to the heavy processing needed for that project. I usually set my latency at 1024 samples for mixing/mastering and I never had dropouts, until now.
I went back to the project tonight after reading your OP and experienced the same dropouts. It stops every time just before the end of the loop and will not repeat. I turned off ARC2 and still had dropouts. I turned off Ozone5 and the dropouts continued. I turned off all plugs/effects. More dropouts. But no issues when not using loops.
Then I went to another project. No problems with dropouts in loops. Then another project, and another. Still no dropouts. So, in my case, I think it's the project, not ARC2. If I find a correlation with the dropouts, I'll post again. Other than this single issue with the one project, my current setup with X3 has been very stable.

That sounds like exactly what's happening at my end - playback stops at the end of the loop and then it hangs. But in my case disabling ARC made the problem go away. I tried re-enabling it a few times and every time the same thing - a hang. I've had other projects with ARC that have had no such problem however, so it sounds like one of those "perfect storm" combinations of things which includes ARC. Do you have any other IK Multimedia plugs in the project in question? 

ARC2 is my only IK plug.
I discovered something interesting today. I made a copy of the problem project. Same dropouts on the loop. Then I started deleting stuff from the copied project until the dropouts went away. I deleted some unused drum tracks from previous recording sessions. That brought my track count down from 42 to 27. Problem resolved! Went back to the original project and archived the unused drum tracks (never know when I might need them!). Problem resolved there too. Deleted copied project and I'm good to go. Lessen learned. Archive unused tracks.
So, my issue seemed to be CPU related. That doesn't help your ARC problem, but ARC was definitely not the issue with me. btw, ARC has given my low end new life with my recordings. Bass traps and other sound treatment could only do so much in my studio.
