tmm crashes with a SIGSEGV when a GTM iRule executes a 'pool' command against Tcl variables that have internal string representations, which can occur when a value is a result of (some) string commands (e.g., 'string tolower') or if the value comes from a built-in iRules command (such as 'class'). For example: when DNS_REQUEST { pool [string tolower "Test.com"] } or: when DNS_REQUEST { pool [class lookup pool-dg key-value] }
Traffic disrupted while TMM restarts.
GTM iRule executes a 'pool' command against Tcl variables that have internal string representations.
Pass the 'pool' argument through 'string trim'. For instance: when DNS_REQUEST { pool [string trim [class lookup pool-dg key-value]] }
tmm no longer crashes on GTM iRules that use the 'pool' command.
