Failed to create a verthash data buffer / only 2 of 8 devices (random) are running #22

I've a reccurring problem to get my rig (8x GTX 1060) running. Each device runs alone; two selected run as a pair, if I add a third device only one or two run (total random); the missed one shows the error:
"Failed to create a verthash data buffer. error code: 2"

That excerpt show the issue.. always the same (random choose of device), even i use a virtual device (two work, a third interrupts the party) " [2021-02-11 14:16:43] INFO 3 miner threads started, using Verthash algorithm.

Failed to create a verthash data buffer means that the are not enough GPU memory. Your WorkSize parameter is very high for GTX 1060 3GB. Try to lower it or use a new "Adaptive Batch Size" feature(implemented in v0.7.0.)
