ASA reloaded automatically

[j.smith@sepidarsystem.com]

Hello

Yesterday we had a problem with our ASAs which are in HA mode. We had ASA 9.9 and suddenly after working on this version for about 1 month, the ASA which was active suddenly reloaded itself and made the second ASA to be active but after 2 or 3 hours the standby ASA which was active reloaded again. It was like a loop and it happend 2 times for every ASA until we decided to upgrade to ASA 9.12. I checked the crash files but found nothing useful. But there was a strange thing in crash file, "Thread Name: Unicorn Proxy Thread-Page fault: Address not mapped". Does anybody knows what could have happened?

Guys, we found out that it was an attack on our devices. I asked and some others had this problem too in other companies.
