Resolution
Repeated Instances of “pseudo-device: devinfo0″ in Messages File
This is a sign of a memory shortage on the system.
When the level of free memory becomes very low the kernel will unload any kernel modules it can, including the devinfo module. However, because the devinfo module is frequently used it will usually be re-loaded very soon afterwards, producing the pair of messages observed.
System memory use should be checked. SunSolve Document: 1009500.1 “Memory usage checking and troubleshooting” can be used as a starting point.
