Hi, Vvectorio means, that the task (in this case three datawriters and a logwriter) runs the internal 'vectorio' Routine. They are waiting for I/O completion. Vvectorio uses 'writev' to write a vector of several pages from different locations in the data cache by a single system call to a continous space on a volume. Other states are 'Vsleep' where the task is blocked by an explicit sleep call or 'Vblockio' which would mean task is waiting for a single block written or read from volume. CU jrg
