Log length problem

Hello everyone, I'm writing you because I recognize a strange problem when i log something, and I don't know if it is a bug or something wanted to work in this way. For a project i need to log some complex information, so i create a string with the info that I need and after that i log it with the command: log(L_INFO "...); But when the length of the string go over 1000 (I get the size with strlen) it is not printed on the log file. I was thinking to split the string to go over the problem, or there is another way? Thanks everyone Mattia
