Hi,
To troubleshoot memory please follow the below steps:
First, please check if the memory usage is genuine or not, this can be checked by checking the memory status of any other similar switch in the network having similar devices attached. This check is important because even a 95% of memory usage could be normal depending upon the requirements of your network.
If the memory usage is really abnormal and the switch is crashing then note the time between the two crashes.
If the two crashes are in  a GAP of 7 days then take the outpust of "show process memory sorted" 5 times at a gap of 24-36 hours.
It will give you an idea about the process which is constantly holding more and more memory without releasing it.
Once you know the process, you can track the relevant bug.
Moreover, on the 2960 switch the 15.X train has a lot of memory bugs, I would recommend you to downgrade it to 12.2(55) train as it is one of the most stable IOS images on this platform.
Thanks.
