In Domino server log, the above message are keep printing, what could be the reason and how can I restrict this?

Answer 1

This is a verbose garbage collection logging report.

Maybe, your server has following setting in notes.ini

JavaVerboseGC=1

This variable enables (=1) or disables (=0) the verbose setting of the Garbage Collector (GC) mechanism in JVM, which causes the JVM to issue many messages about memory usage as GC runs. JavaVerboseGC=1 enables this setting, which can help you troubleshoot problems.
