We are using Java 6 (stuck with CentOS 5.8 at this time) and Tomcat 7.0.64. Xmx is 5G, Xms is 2G, and GC options are -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode No other custom memory-related settings are in place. Looking at the GC log, the last few Full-GC entries are: 1367.020: [Full GC 1367.020: [CMS: 1178831K->527456K(1926784K), 2.1117220 secs] 1250378K->527456K(2080128K), [CMS Perm : 169762K->56187K(169984K)] icms_dc=0 , 2.1118160 secs] [Times: user=1.96 sys=0.13, real=2.11 secs] 2579.317: [Full GC 2579.317: [CMS2581.876: [CMS-concurrent-mark: 2.558/1212.733 secs] [*Times: user=113.05 sys=28.01, real=**1212.49 **secs] ** * 3539.969: [Full GC 3539.969: [CMS3540.056: [CMS-concurrent-sweep: 1.571/23.223 secs] [Times: user=6.12 sys=1.36, real=*23.21 secs*] 4070.456: [Full GC 4070.457: [CMS: 1252569K->591200K(1926784K), 2.3447040 secs] 1270617K->591200K(2080128K), [CMS Perm : 169983K->56598K(169984K)] icms_dc=0 , 2.3448140 secs] [Times: user=2.18 sys=0.14, real=2.34 secs] What can we do?
