please stay away from c2960-lanbasek9-mz.150-2.SE4.bin

when you upgrade your Cisco switches please stay away from c2960-lanbasek9-mz.150-2.SE4.bin
some memory leak issue with that IOS, you will lose management function and console login, power recycle is the the only solution, please go to c2960-lanbasek9-mz.150-2.SE5.bin.

my 2960G box with c2960-lanbasek9-mz.150-2.SE5.bin is working well so far after 1 week running
