HP STP Port Blocking

I have a stack of switches that seems to be running slow, i've recently checked the logs and i'm getting these random logs that show STP is blocking and unblocking random ports, please note that the pictures are only for a shor ttime period each day it seems to be a different set of ports

Some clients lower ethernet link speed when entering low power / sleep mode/power off.  This might result in STP messages like these

Those log lines look normal - that's how STP works:

- port comes up
 - STP blocks
 - STP goes through listening/learning stages
 - STP starts forwarding.

You'll get that every time an interface comes up, eg when people start up their PCs etc...
