Hi,
after switching to 11.7 I get following after mining approximately half an hour:
Miner cannot initialize for 5 minutes, need to restart miner!
����������������������������������������������������������������ͻ
� Claymore's Dual GPU Miner - v11.7 �
� ETH + DCR/SIA/LBC/PASC/BLAKE2S/KECCAK �
����������������������������������������������������������������ͼ
ETH: 1 pool is specified
Main Ethereum pool is eth-eu1.nanopool.org:9999
At least 16 GB of Virtual Memory is required for multi-GPU systems
Make sure you defined GPU_MAX_ALLOC_PERCENT 100
Be careful with overclocking, use default clocks for first tests
Press "s" for current statistics, "0".."9" to turn on/off cards, "r" to reload pools, "e" or "d" to select current pool, "x" to select GPU, "z" to find best -dcri values
OpenCL initializing...
AMD ADL library not found.
Any help would be highly appreciated.

same issue with 11.7 under ubuntu 16.04
Try adding:
#GPU_FORCE_64BIT_PTR 0
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100
export GPU_SINGLE_ALLOC_PERCENT=100
Even with this environment variables miner stops after approximately 20 h with the same message. I also have Ubuntu 16.04
What do the logs show? (Immediately before this event?)
How many GPU are you mining with?
I've had a few instances (win10) where something locked up, sometime with a BSOD, sometimes total system freeze, hard-reset required, and on next init, AMD drivers are "missing", (openCL) in my case.
(This is also mentioned in the readme)
I've also had a few cases, (after flashing BIOS), where cards were not stable, or rather not performing as well as I expected, and a FULL shutdown, bleed-down solved that.
Shutdown OS, wait until it's off, pull the power input cables from the PSUs, (leave the PSUs ON), then press the power on button, hold it in for 20sec.
Big PSUs will have a lot of power held in caps, this will keep circuits alive for some minutes after power cables are removed.
Holding the power button down, will try to enable power, and the hardware will rapidly bleed down all residual power, (if you have some BIOs LEDs on the mb, keep holding the power button depressed, until those are all out, wait 10 more sec, release).
Power OFF PSUs, attach power cables, switch on, and press the power button.
The above is good general advice prior to digging into instability issues, (make sure you have a clean start etc).
In my case, (openCL missing) After a lot of debugging, I
think the cause was hardware related. One of the challenges as you add more GPUs, risers, cables, pcie cards etc, you're adding a lot of connections, only one needs to be suboptimal, and you're in trouble, and have a lot of things to check.
If you hit the wall, I'd suggest break it down, divide and conquer. Assuming you have 4 GPU, remove half of them, (power cable to riser, "usb" cable, power to GPU).
Run with that, if you don't have an issue about 1 hour, (3 times the previous event period (you mentioned 20min), then add 1 more GPU, etc.
If you still see the issue with only 2 GPU, remove all but 1, and try again.
It's also very easy with rigid "USB" cables to slightly tip, dislodge the PCIe card in the slot. *TIP* Get some nylon stand-offs, and string your PCIe cards together, I use these, and since doing this, my rigs have stabilised a LOT!https://www.amazon.co.uk/Malayas-Stand-off-Assortment-Electronics-Computers/dp/B01M9AY5Z6/ref=sr_1_2?ie=UTF8&qid=1525179057&sr=8-2&keywords=nylon+standoffsThe above kit, has various lengths, so you can assemble the spacing to match the socket pitch on your motherboard. They are nylon, so soft, won't damage the tracks, or expand with heat, stress the boards etc.
Sure, it's not so easy to swap out a bad board, when it's chained up, but at least 2 boards I thought were bad, have been running fine for weeks, (now they are secure in the sockets).
Visually inspect them when using for the first time.
I should add, all the above assumes you are actually mining ok for the first 20min, that being so, probably your config is ok, and you're looking at a hardware related issue, (or have some other application starting around the 20min mark).
Good luck./
