Thanks Tanel! Just to follow up on he same, I see a lot of the following when I query x$ksmlru on hourly basis: KSMLRCOM KSMLRSIZ KSMLRNUM session param valu 27,480 656 0 session param valu 27,480 8 0 session param valu 27,480 504 0 session param valu 27,480 151 0 It seems that these cause a lot of flushes. Are these chunks of type "freeable"?
