Hi,
is there any advice / best practice on how to debug neo4j locking? I am having trouble with a larger web service application that goes all single threaded. According to strace, it looks like neo4j gets stuck in memory mapping (i.e. there are batches of madvise and mprotect calls followed by longer pauses). Any help will be much appreciated.
Thanks!

Not sure (I'm a single-threaded guy) but Matthias says
System.out.println() is your friend :)
Michael, do you have any tips?

If you can write, you can code - @coderdojomalmo
If you can sketch, you can use a graph database - @neo4j
