Is it ipossible to change the row height through jasper studio? Currently i display 20 rows in a page. I want to increase it to let us say 30. I want to achieve it by decreasing the row height and reducing the font size. i can reduce the font size, however when i try to reduce the row height (from 20px to 15px) i get the below warning in properties pane. "resize or movement operations are not allowed by container layout" How can i achieve this? Am using jasper studio 6.3.0

Issue occurs again after a week!!!! I have the below heap size confirguration for the jasper server. -Xms2048m -Xmx6144m -XX:MaxMetaspaceSize=512m But still I get the overhead limit exceeded error after a week of last restart. 28-Aug-2016 15:46:07.171 SEVERE [http-nio-8080-exec-210] org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun java.lang.OutOfMemoryError: GC overhead limit exceeded 28-Aug-2016 15:48:16.927 SEVERE [http-nio-8080-exec-213] org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun java.lang.OutOfMemoryError: GC overhead limit exceeded 28-Aug-2016 15:56:08.809 SEVERE [79457] org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun java.lang.OutOfMemoryError: GC overhead limit exceeded 28-Aug-2016 15:56:55.653 SEVERE [http-nio-8080-exec-212] org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun java.lang.OutOfMemoryError: GC overhead limit exceeded 28-Aug-2016 15:57:40.161 SEVERE [http-nio-8080-ClientPoller-1] org.apache.tomcat.util.net.NioEndpoint$Poller.run java.lang.OutOfMemoryError: Java heap space Can anyone help me please ? Number of calls to the server per day is between 4500 and 7000

Thanks a lot!! i changed this as per your advice. Will observe server for a week from now. Generally memory leaks happens and server goes down 3-5 days after the restart here.

I have set the heap size of tomcat as below... export CATALINA_OPTS="$CATALINA_OPTS -Xms1024m" export CATALINA_OPTS="$CATALINA_OPTS -Xmx4096m" export CATALINA_OPTS="$CATALINA_OPTS -XX:MaxPermSize=512m" in the file /usr/share/tomcat/bin/catalina.sh Hope this will help. Tomcat used to go down once in every 3-5 days . I will observe server in coming days. Thanks a lot for the help!!

Thank you for your response. no am using linux server. i tried to set up the heap size. but it shows below message.. 18:12:42 [root@jasper2 /srv/tomcat/webapps/jasperserver/WEB-INF/classes] # java -XX:PermSize=256m -XX:MaxPermSize=4000m JavaApp OpenJDK 64-Bit Server VM warning: ignoring option PermSize=256m; support was removed in 8.0 OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=4000m; support was removed in 8.0 Error: Could not find or load main class JavaApp Moreover i am not sure this heap size is being used by system.

There are around 2000 report request per day to the server.. initial heap size is about 132M and Max heap size is about 2G. But not sure server is using JVM heap size parameters..

We are encountering memory leak issues with our jasper server. This is a recurring issue now and happens every 5 days or so. We upgraded the RAM to 8GB (for the server) and still this happens. Below is the excerpt from the tomcat server log. 12-Aug-2016 11:15:02.973 SEVERE [http-nio-8080-Acceptor-0] org.apache.tomcat.util.net.NioEndpoint$Acceptor.run java.lang.OutOfMemoryError: Java heap space at java.nio.HeapByteBuffer.<init>(HeapByteBuffer.java:57) at java.nio.ByteBuffer.allocate(ByteBuffer.java:335) at org.apache.tomcat.util.net.NioEndpoint$NioBufferHandler.<init>(NioEndpoint.java:1393) at org.apache.tomcat.util.net.NioEndpoint.setSocketOptions(NioEndpoint.java:547) at org.apache.tomcat.util.net.NioEndpoint$Acceptor.run(NioEndpoint.java:697) at java.lang.Thread.run(Thread.java:745) 12-Aug-2016 11:19:58.936 SEVERE [http-nio-8080-exec-10] org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun java.lang.OutOfMemoryError: Java heap space 12-Aug-2016 11:20:06.648 SEVERE [http-nio-8080-ClientPoller-1] org.apache.tomcat.util.net.NioEndpoint$Poller.run java.lang.OutOfMemoryError: Java heap space 12-Aug-2016 11:20:09.945 SEVERE [http-nio-8080-ClientPoller-0] org.apache.tomcat.util.net.NioEndpoint$Poller.run java.lang.OutOfMemoryError: Java heap space Can you please guide me on this. Please let me know if you need more details.
