Off lately I have been running into PermGenSpace Out of memory errors.
07/15/2010 20.08.12 java.lang.OutOfMemoryError: PermGen space After reading few posts I even start the tomcat using the following parameter: -Djava.awt.headless=true -Dfile.encoding=UTF-8 -server -XX:NewSize=512m -XX:MaxNewSize=512m -XX:PermSize=512m -XX:MaxPermSize=512m -XX:+DisableExplicitGC I'm using the following: Apache Tomcat/6.0.24 Apache httpd: Apache/2.2.15 (Win32) mod_ssl/2.2.15 OpenSSL/0.9.8m mod_jk/1.2.30 JVM - 1.6.0_18-b07 - 64 bit SUN implementation Windows Server 2008 R2 - 64 bit This error keeps occurring at least once every day. I don't even see much load on the server either (about 30 simultaneous connections at any given time). Is there anything I'm missing or have overlooked. Any help would be appreciated. Here is my memory utilization: Memory MXBean Heap Memory Usage init = 4294967296(4194304K) used = 736729304(719462K) committed = 4288348160(4187840K) max = 11453267968(11184832K) Memory MXBean Heap Memory Usage init = 4294967296(4194304K) used = 736729304(719462K) committed = 4288348160(4187840K) max = 11453267968(11184832K) Memory MXBean Heap Memory Usage init = 4294967296(4194304K) used = 736729304(719462K) committed = 4288348160(4187840K) max = 11453267968(11184832K) Memory MXBean Heap Memory Usage init = 4294967296(4194304K) used = 736729304(719462K) committed = 4288348160(4187840K) max = 11453267968(11184832K) Memory MXBean Heap Memory Usage init = 4294967296(4194304K) used = 736729304(719462K) committed = 4288348160(4187840K) max = 11453267968(11184832K) Non-Heap Memory Usage init = 24313856(23744K) used = 95717208(93473K) committed = 97452032(95168K) max = 138412032(135168K) Memory Pool MXBeans Code Cache Type Non-heap memory Usage init = 2555904(2496K) used = 12208704(11922K) committed = 12386304(12096K) max = 50331648(49152K) Peak Usage init = 2555904(2496K) used = 12211200(11925K) committed = 12386304(12096K) max = 50331648(49152K) Collection Usage null PS Eden Space Type Heap memory Usage init = 1073807360(1048640K) used = 690843320(674651K) committed = 1418395648(1385152K) max = 4281925632(4181568K) Peak Usage init = 1073807360(1048640K) used = 1428750336(1395264K) committed = 1428750336(1395264K) max = 4292214784(4191616K) Collection Usage init = 1073807360(1048640K) used = 0(0K) committed = 1418395648(1385152K) max = 4281925632(4181568K) PS Survivor Space Type Heap memory Usage init = 178913280(174720K) used = 0(0K) committed = 6619136(6464K) max = 6619136(6464K) Peak Usage init = 178913280(174720K) used = 27544328(26898K) committed = 178913280(174720K) max = 178913280(174720K) Collection Usage init = 178913280(174720K) used = 0(0K) committed = 6619136(6464K) max = 6619136(6464K) PS Old Gen Type Heap memory Usage init = 2863333376(2796224K) used = 45885984(44810K) committed = 2863333376(2796224K) max = 8589934592(8388608K) Peak Usage init = 2863333376(2796224K) used = 59115592(57730K) committed = 2863333376(2796224K) max = 8589934592(8388608K) Collection Usage init = 2863333376(2796224K) used = 45885984(44810K) committed = 2863333376(2796224K) max = 8589934592(8388608K) PS Perm Gen Type Non-heap memory Usage init = 21757952(21248K) used = 83508504(81551K) committed = 85065728(83072K) max = 88080384(86016K) Peak Usage init = 21757952(21248K) used = 83508504(81551K) committed = 85262336(83264K) max = 88080384(86016K) Collection Usage init = 21757952(21248K) used = 83500864(81543K) committed = 85065728(83072K) max = 88080384(86016K) Thanks, __________________________________ Anurag 301-296-3838 *** Please note my email address has changed.
