logomatic v2, out of memory error

hello,

i m currently working on a project using a javelin stamp board, a GPS, a LCD from parallax and the logomatic v2 data logger. everything is going well at the beginning… GPS acquiring data, sending them to the LCD and the memory, however, the memory stop recording the data every time,randomly (whatever the memory is logging), when the file is equal to 18kbytes.

does someone has already have this problem? or if someone has any idea where it could come from it would be more than welcome.

thanks

Matthieu
