I've seen several boxes running 15.0(2)SE and rebuilds suddenly die with memory problems. The box would be fine for many months, then one day the monitoring system would show that it had suddenly started losing ~1% memory per hour and then would crash a couple of days later with OOM. I caught one in the act last week, and "show memory" suggested that the dot1x process was chewing up fragments all over the place. dot1x was disabled on that switch. Am currently installing 15.2 on new boxes as it provides much better support for ipv6 neighbor security. Haven't run into any major problems yet. Also the OP should note that when you boot from from 12.2(52)SE to a later versions, the boot loader will almost do a microcode upgrade on the C3560X platform. Depending on the version involved, this can take up to 35 minutes downtime per box. The release notes still don't mention this as a risk, which is not good. It would be very helpful if cisco provided some information on this in the release notes.
