I wouldn't concern much for the memory unless the switch starts to give mem-alloc error. If you're unable to do commands like "show run" or "show int desc" or unable to make new configuration, this is indicative of a memory leak. Cisco IOS switch does not have memory leak, it is considered a bug. So if you do run in to such symptom, a reload of the switch will resolve the problem for quite a while. Otherwise, if it is concern, upgrading the IOS will address this.
If you check your memory "show memory | inc fragment" , if you have an excessive amount of fragment, this can also cause error and will be resolved by a reboot. I have seen some IOS products with even over 15,000 fragment in memory and still work in reasonable capacity.
Now keep in mind, if you try to upgrade IOS, you may not have sufficient space for this. If you'd like to free up space you can check your flash for useless/unwanted files.

@ Tom, well I have tried different commands and they all work fine until I tried this:
Not enough free memory to launch Tcl shell
So yes there seems to be some error and a restart might be required.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
