I do many test, seems found the problem is the meta points.
i have 7000 points ,and ,more then 1000 meta datapoints. I think if have a max count limit with meta points? or anything else ,thanks.

There is no max number of points for Mango but could be for your hardware. Can you tell us what version of Mango you are running? We have seen this happen before and have fixed this in Mango 2.5.0. There will be a beta version available very soon that should solve this for you.

this is an old project ,I use the version 1.12.5 and i update the serotonin-timer.jar to m2m2 version 2.4.0 and modify some code. I will test the version v 2.5.0.
