memory usage grows up daily in unexpected way

Did you ever find an answer to your memory leak? I too am seeing a similar memory leak in my iRules in 10.1.0. The memory consumption rate is steady- not tied to traffic load. I'm showing similar numbers in my tmctl output:

name allocated max_allocated held size

tcl (variable) 376576032 376680192 376576032 1
