Currently I am facing issues, that the java melody statistics running for a grails application having some “gaps” (for all graphs at the same time!). I cannot see any issues from the logs and the server seems to be running fine within those gaps. The gaps seem to appear at any time, I cannot figure out any systematics.


JDK: jdk1.6.0_25
Application server: Tomcat 6.0.33
OS: Debian 2.6.32-028stab094.3
Grails: 1.3.7
Grails Java Melody Plugin-version: 1.5
What can be the reason for this?
When does java melody stops recording values? Running out of threads, out of memory?
The server has ran out of open file handles and could not write statistics to disk.
