Hi experts,
I run our 19 application servers with configuration like below for about 5 months without any problems(CPU utilization is always below 20%).I find wait time in ST03 of dialog work processes increases significantly and intermittently recently. I check dev_disp and find error messages like this. I plan to increase dialog work processes from 20 to 30(according to the note 39412) and update kernel 721_EXT from 136 to 316 and hope this works. Any opinions?
PS: By the way, rdisp/queue_size_check_value use default value = on,50,30,40,500,50,500,80
