Dear all,

first of all, excuse me if you receive this issue 2 times, but I've sent it before subscribing and I was not sure it was accepted.

I have deployed 10 applications in Tomcat/Spring and each one contains logback in order to have a different log file for each application.

When I look at tomcat threads, I see 8 threads per application (named logback-1 to logback-8).

Does anyone know why 8 and how to reduce that number ? (and the consequencies) ? 
8x10 is much ...

thanks in advance for any help,
Samuel
