stack trace of the JVM crash

Hi,

I've a server running with a Tomcat6 + some web application.

The JVM was running by 15 days when it unexpectedly crashed on a
malloc_consolidate

No idea on how to reproduce it, I've already contacted who could have been
working on the webapp while it crashed to know if they were using it and what
were they doing to get some hint, if I get anything out of this I'll add a
comment.

Here's the head of the stack trace log (full log attached)
