I have had a few students trigger the error Guru Meditation -2304 (VERR_REM_TOO_MANY_TRAPS) when modifying the schedulers in the guest. What does this error mean? What are possible causes? The only fix I have found is to reinstall the system. This is on Version 1.5.6 (Cannot upgrade at the current time), Redhat RHEL5 Update 1 64-bit AMD host. Other common errors seen when the crashes happen are: VERR_REM_TOO_MANY_TRAPS -> uTrap=d error=30 next_eip=00000055 eip=00000055 cr2=00000000 ERROR [COM]: aRC=0x80004005 aIID={fd443ec1-0006-4f5b-9282-d72760a66916} aComponent={Mouse} aText={Could not send the mouse event to the virtual mouse (VERR_PDM_NO_QUEUE_ITEMS)} aPreserve=false ERROR [COM]: aRC=0x80004005 aIID={fd443ec1-000a-4f5b-9282-d72760a66916} aComponent={Keyboard} aText={Could not send scan code 0x000000C5 to the virtual keyboard (VERR_PDM_NO_QUEUE_ITEMS)} aPreserve=false",defect,closed,VMM,VirtualBox 1.5.6,fixed,,,other,other
