About a year and a half ago, I found that there I was getting memory 
fragmentation, which caused RTEMS to lock up.

I had a class of about eight bytes in size, and allocated and 
deallocated an object of this class 100 times every second. There was 
only ever  two objects active at any one time.

After about three days, RTEMS locked up and had to be rebooted. I 
overcame this by overloading operators new and delete in the class and 
made a memory manager for the class.  I have run it for two weeks 
without a problem now.

I am bring this up now because I am writing up my thesis and has come to 

Has memory fragmentation been resolved or considered for RTEMS apart 
from partitioning?
