Hello, While running a stress test of Linux' iSCSI initiator I noticed that the test ran fine over an Ethernet network but that strange memory allocation problems were reported after I switched from Ethernet to IPoIB. A few minutes later the whole system froze. Anyone any hints on how I can pinpoint the cause of this issue ?
