The current Mcko= i implementation seems to keep lots of files open, and in large deployments= , it causes the JVM to fail with a "too many open files" error. My database= uses about 250 tables, and I create a separate database instance for each = customer in hosted mode. This seems to imply (I'm guessing here) that Mckoi= opens n*250 files when there are n instances, and that causes problems wit= h the JVM. This is unfortunately a show-stopper for me. =0A=0AI am hoping t= hat you will have addressed this problem with the new version.=0A=0AMckoi h= as proven to be an extremely reliable, easy-to-use piece of software.
