APD crashes when processing an access policy with Tcl expressions.
Rare APD crash with core, which might cause brief authentication outage.
This happens very rarely; the chance is greater with a higher number of Tcl expressions with session variables in APM configurations. APD must be processing an access policy with Tcl expressions using session variables while the administrator makes a configuration change to one of the policies containing Tcl expressions.
None
APD no longer crashes when processing an access policy with Tcl expressions; previously, this occurred rarely.
