I am just trying to learn and understand the GC logs. (I did read the sun's docs on GC tuning).
jdk1.6.0_07 -Xms2g -Xmx2g -Xss256k -XX:+UseLargePages -XX:+PrintGCDetails -verbose:gc -Xloggc:/var/log/gc.log -XX:PermSize=512m -XX:MaxPermSize=512m It is running Parallel Collector by default. The full GC usually runs in every 20-30 minutes (takes 2 seconds), and the minor collections occur every 40-50 seconds. I viewed the logs in GC Viewer, and the throughput is about 99.6%, but the pauses tend to get noticable at times slowing the app down for upto 10 minutes- and sometimes the app becomes unresponsive after running for about a week due to GC. I have pasted the snipped from my GC logs (when the pause became noticeable). Does the logs in themselves indicates any possible problems? Thanks in advance. 322241.484: [GC [PSYoungGen: 493731K->50938K(578816K)] 1617970K->1175624K(1977600K), 0.0761440 secs] [Times: user=0.23 sys=0.00, real=0.07 secs] 322264.254: [GC [PSYoungGen:
