Hi, I have running Tomcat 3.2.1 on a real server but it get more and more memory and at the end the system slow so much that you must killall java processes 'cause you cannot even restart tomcat 'cause doesn't restart, this happens using mod_jk under apache seems that the garbage collector is not working and is leaving sections opened, my system is Red Hat Linux 7.1 Professional Server, and the site is: www.cubaonline.cu, I changed to my old configuration using mod_jserv and seems to be working but I would like to hear some comments about it... This is the screen I got since I changed from mod_jk to mod_serv but I want to know if this is normal: 6:58pm up 4 days, 10:02, 1 user, load average: 0.00, 0.00, 0.00 77 processes: 76 sleeping, 1 running, 0 zombie, 0 stopped CPU states: 0.1% user, 0.7% system, 0.0% nice, 99.0% idle Mem: 255568K av, 244224K used, 11344K free, 0K shrd, 55316K buff Swap: 265032K av, 32K used, 265000K free 102396K cached PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND 28182 root 9 0 30724 30M 2840 S 0.0 12.0 0:01 java 28192 root 8 0 30724 30M 2840 S 0.0 12.0 0:00 java 28193 root 9 0 30724 30M 2840 S 0.0 12.0 0:00 java 28194 root 9 0 30724 30M 2840 S 0.0 12.0 0:00 java 28195 root 9 0 30724 30M 2840 S 0.0 12.0 0:00 java 28196 root 9 0 30724 30M 2840 S 0.0 12.0 0:00 java 28197 root 9 0 30724 30M 2840 S 0.0 12.0 0:00 java 28206 root 9 0 30724 30M 2840 S 0.0 12.0 0:00 java 28207 root 9 0 30724 30M 2840 S 0.0 12.0 0:00 java 28208 root 9 0 30724 30M 2840 S 0.0 12.0 0:00 java 28209 root 9 0 30724 30M 2840 S 0.0 12.0 0:05 java 28210 root 9 0 30724 30M 2840 S 0.0 12.0 0:13 java 28211 root 9 0 30724 30M 2840 S 0.0 12.0 0:00 java 28280 root 9 0 30724 30M 2840 S 0.0 12.0 0:09 java 29553 apache 9 0 6664 6664 6408 S 0.0 2.6 0:00 httpd 29430 apache 9 0 6652 6652 6308 S 0.0 2.6 0:00 httpd 29515 apache 9 0 6648 6648 6392 S 0.0 2.6 0:00 httpd 29535 apache 9 0 6648 6648 6312 S 0.0 2.6 0:00 httpd 29551 apache 9 0 6648 6648 6388 S 0.0 2.6 0:00 httpd 29552 apache 9 0 6648 6648 6352 S 0.0 2.6 0:00 httpd 29599 apache 9 0 6648 6648 6392 S 0.0 2.6 0:00 httpd 29349 apache 9 0 6644 6644 6304 S 0.0 2.5 0:00 httpd 29640 apache 9 0 6632 6632 6396 S 0.0 2.5 0:00 httpd 29641 apache 9 0 6632 6632 6396 S 0.0 2.5 0:00 httpd 29485 apache 9 0 6620 6620 6392 S 0.0 2.5 0:00 httpd 29598 apache 9 0 6620 6620 6392 S 0.0 2.5 0:00 httpd 29614 apache 9 0 6620 6620 6392 S 0.0 2.5 0:00 httpd 28223 root 9 0 6460 6460 6284 S 0.0 2.5 0:00 httpd 915 xfs 9 0 4732 4732 896 S 0.0 1.8 0:00 xfs 24583 named 9 0 4200 4200 2196 S 0.0 1.6 0:00 named 24584 named 9 0 4200 4200 2196 S 0.0 1.6 0:00 named 24585 named 9 0 4200 4200 2196 S 0.0 1.6 0:03 named 24586 named 9 0 4200 4200 2196 S 0.0 1.6 0:00 named Java is getting and getting more memory, I didn't see yet the maximun memory that it takes, it is supposed to get some climax and after it to be aroung that memory... My questions is: Is that processes running taking all this memory normal ? Thanks a lot for the answers... Guido. P.D: I'm using virtual hosts and one JVM for my site...
