Possible Sudden Uptick in ASA DOS?

Come in this morning to find one failover pair of ASA's had the primary crash and failover, then a couple hours later, the secondary crash and failover, back to the primary. Another pair running the same code had the primary crash and fail in the same time window. So, three crashes in 4 hours in our environment. Open a TAC case on one of these for post-mortem analysis, and they interpreted the crash dump to point at a DOS bug first published in Oct. The very interesting thing; on the phone the TAC engineer said this was "the 10th one of these I've dealt with this morning". Here's the bug they reference: https://tools.cisco.com/bugsearch/bug/CSCul36176/?reffering_site=dumpcr Anyone else have observations to add on this?
