Hello Norberto,

you may need to reload the switch to actually free memory.


However, the correct solution is an IOS image upgrade to an IOS image where the bug is fixed


if you have access to the bug  info you can easily find the list of fixed-in images (minimal versions)


Hope to help

Giuseppe
