Having been on 8.0.110.0 for a while now, we've seen no real issues so far (apart from a continuing AP client counting bug). However, like 8.0.100.0, it has got memory leaks. The amount of free memory on the 5508s has steadily been decreasing. The 8510 free memory has been flat, which could be no leak, or just the leak is invisible out of 16Gb RAM... The memory leak did cause an issue when upgrading. We put the 110 image on in the morning to reboot that night, and one 5508 rebooted in the afternoon, which we believe to be out of memory. We had errors when uploading, it reported using a "slow transfer mode" due to lack of free RAM. If you're plotting memory usage, might be worth checking that. We did have two 5508s spontaneously reboot on 8.0.100.0. The third 5508 didn't and is the only one that had been physically powered off before the upgrade as it moved location (the other two were rebooted into the new version). No issues on the 8510. These were diagnosed to be caused by a bug in AVC (CSCuq97965) which is supposed to have been fixed in 8.0.110.0.
