Strange Summit400-48t issue

I have several Summit400-48t running in our environment and in the last
two weeks I have had two that seem to temporarily stop learning
mac-address and become very slugish (ping response times from local lan
range from 50ms to 700ms) until they are rebooted. Both of the switches
that experienced this issue were running 7.5e.2.6 [ssh] and had an
uptime of 7+ months before they experienced this issue. On this last
switch I was able to do a show tech-support all before I had to reboot
the device. The only thing that jumped out at me was the show memory
output showed the free blocks (not sure if I'm reading the output right)
were over 40,000 while all our other switches show that value around
50. I haven't been able to find out exactly what that means, does anyone
have any idea?

Switch internal memory detail:

If there is any other output from the show tech that would be helpful in
figuring this issue out let me know and I will provide it.
