Perhaps NewGen perhaps PermGen. What does JVM logging that is partly enabled
indicate? What JVM version? It is JRun that is CPU bound?
You have some very specific JVM arguments there. Couple things I note with New
/ Young Generation and Permanent Generation. Sometimes with a largish initial
heap memory configuration ie bigger than 1Gb (Xms) I have seen Java not settle
to a good workable value, you may do well to specify a size. The value depends,
you could try -Xmn148m. There is no setting for initial Permanent Generation so
you could add âXX:PermSize=192m .
JVM logging seems to be partly there (-XX:+PrintGCDetails
-XX:+PrintGCTimeStamps) â what is your thoughts on the two logging switches
without the output to a log file (eg -XX:+PrintGCDetails -XX:+PrintGCTimeStamps
-XX:+PrintHeapAtGC -verbose:gc -Xloggc:cfjvmGC.log)?
I guess you are on CF9.0.1 64 bit? Would that be JVM version 1.6.0_17?
HTH, Carl.
