serial or coll object problem

Hi,

I have an arduino sending numbers (from sensors) to Max.
The arduino is sending a list of 10 X 10bits number + timecode at around 66Hz
I record all the “raw” data in a coll.
It works fine for some time, but when I get around 150000 “samples” (around 37min of recording) I start to have glitches.
I need to be able to record at least 1h

Each coll line is a list of 1 string + 11 numbers.
See the example below.
But some lines get shorter, some longer…
(the last number on the line is a time in ms, so it looks like the glitches have something to do with incoming data, they repeat or jump)

Does anybody have an idea what it could be ?

Additional question:
What is the serial buffer exactly ? Could the problem come from that ?
I tried to increase it but it didn’t change…

Thank you

Yoann
