In the pingaccess, when the HUDCTL_TEARDOWN arrives and is forwarded synchronously down the chain, this causes the flow to be removed and the chain to be torn down. This also causes the CLIENT_CLOSED to be called. Coincidentally customer has iRule, and happens to need a block matching the size of the just-freed block containing ctx, thus the freed ctx is overwritten with the log message generated due to the debugging TCL variable being "1". Upon reaching lower filters, the pingaccess attempts to call pmgr_service_update_last_active where the issue occurred. This issue can be seen in the 1001041 bug.
Unexpected failover occurred which impacted accessing applications.
APM provisioned. Using multiple ping access instances, the Ping access feature is mainly used for SSO.
