Exception in log files under heavy load




Hey,

I am getting the following exception under heavy load:

Disabling lateral cache due to error Failed to put

I guess there is a not synchronized access to a hashmap that should be
synchronized somewhere...

What version of JCS are you using?

Are you using groups?

Are you using partial key removal--ending a string key in ":"?
