Hello James,something quite interesting happened during my stability tests. GPLPV 0.11.0.213 which I consider stable, showed the same hang as the newer GPLPV versions. I now try to find out why even the stable 0.11.0.213 hangs when it was and is stable on our production systems. There are 3 possible causes: Xen 4.1.1 vs Xen 4.0.1, dom0 2.6.32.36 vs 2.6.32.18 and CPU Xeon E3-1230 vs Xeon X3450 [and board X9SCM-F vs. X8SIL-F]. The attached log show debugkeys for the hang. I find lines 64-66 quite interesting where is shows that there is an event channel upcall pending on the hung VM2, no problems on VM1 (line 52-54). Could that be a hint to the real problem? Regards Andreas
