Hello,
I am trying to run database software in Sniper. Some that I've tried are memcached, mongodb, and redis. All three appear to hang. Sniper prints out:
[SNIPER] Start
[SNIPER] --------------------------------------------------------------------------------
[SNIPER] Sniper using Pin frontend
[SNIPER] Running full application in DETAILED mode
[SNIPER] --------------------------------------------------------------------------------
[SNIPER] Enabling performance models
[SNIPER] Setting instrumentation mode to DETAILED
And doesn't print anything else. Does anyone have any ideas about why this would happen?
Thanks,
Patrick

If you run memcached with -vvv you'll get the following output

I've managed to pinpoint the hang at thread.c:1127 however it hangs at a later iteration of the loop, and the iteration it hangs in varies between runs. Sniper outputs this line when it hangs:
[CONTROLLER] tid: 1 ip: 0x4fb306 5122776 Start
