Hi! Always, when I’m trying to watch Console: [quote]HTTP Status 500 - Filter execution threw an exception type Exception report message Filter execution threw an exception description The server encountered an internal error that prevented it from fulfilling this request. exception javax.servlet.ServletException: Filter execution threw an exception root cause java.lang.OutOfMemoryError: Metaspace note The full stack trace of the root cause is available in the Apache Tomcat/6.0.36 logs. Apache Tomcat/6.0.36[/quote] And sometimes (60-70 %) when I’m trying to Edit Modbus RTU over TCP Device: [quote]HTTP Status 500 - Filter execution threw an exception type Exception report message Filter execution threw an exception description The server encountered an internal error that prevented it from fulfilling this request. exception javax.servlet.ServletException: Filter execution threw an exception root cause java.lang.OutOfMemoryError sun.misc.Unsafe.allocateMemory(Native Method) java.nio.DirectByteBuffer.(Unknown Source) java.nio.ByteBuffer.allocateDirect(Unknown Source) sun.nio.ch.Util.getTemporaryDirectBuffer(Unknown Source) sun.nio.ch.IOUtil.write(Unknown Source) sun.nio.ch.FileChannelImpl.writeInternal(Unknown Source) sun.nio.ch.FileChannelImpl.write(Unknown Source) org.apache.wicket.pageStore.DiskDataStore$SessionEntry.savePage(DiskDataStore.java:349) org.apache.wicket.pageStore.DiskDataStore.storeData(DiskDataStore.java:181) org.apache.wicket.pageStore.AsynchronousDataStore.storeData(AsynchronousDataStore.java:228) org.apache.wicket.pageStore.DefaultPageStore.storePageData(DefaultPageStore.java:120) org.apache.wicket.pageStore.DefaultPageStore.storePage(DefaultPageStore.java:154) org.apache.wicket.page.PageStoreManager$PersistentRequestAdapter.storeTouchedPages(PageStoreManager.java:383) org.apache.wicket.page.RequestAdapter.commitRequest(RequestAdapter.java:171) org.apache.wicket.page.AbstractPageManager.commitRequest(AbstractPageManager.java:98) org.apache.wicket.page.PageManagerDecorator.commitRequest(PageManagerDecorator.java:73) org.apache.wicket.page.PageAccessSynchronizer$2.commitRequest(PageAccessSynchronizer.java:281) org.apache.wicket.Application$2.onDetach(Application.java:1628) org.apache.wicket.request.cycle.RequestCycleListenerCollection$3.notify(RequestCycleListenerCollection.java:105) org.apache.wicket.request.cycle.RequestCycleListenerCollection$3.notify(RequestCycleListenerCollection.java:101) org.apache.wicket.util.listener.ListenerCollection$1.notify(ListenerCollection.java:120) org.apache.wicket.util.listener.ListenerCollection.reversedNotify(ListenerCollection.java:144) org.apache.wicket.util.listener.ListenerCollection.reversedNotifyIgnoringExceptions(ListenerCollection.java:113) org.apache.wicket.request.cycle.RequestCycleListenerCollection.onDetach(RequestCycleListenerCollection.java:100) org.apache.wicket.request.cycle.RequestCycle.onDetach(RequestCycle.java:593) org.apache.wicket.request.cycle.RequestCycle.detach(RequestCycle.java:542) org.apache.wicket.request.cycle.RequestCycle.processRequestAndDetach(RequestCycle.java:285) org.apache.wicket.protocol.http.WicketFilter.processRequest(WicketFilter.java:188) org.apache.wicket.protocol.http.WicketFilter.doFilter(WicketFilter.java:245) note The full stack trace of the root cause is available in the Apache Tomcat/6.0.36 logs.

Did you see “java.lang.OutOfMemoryError” ? You need to edit your wrapper configuration to allow more memory, and/or get a server with more memory. ---

[quote=“pturmel”]Did you see “java.lang.OutOfMemoryError” ? You need to edit your wrapper configuration to allow more memory, and/or get a server with more memory.[/quote] Thanks for an answer! Can you write where to find this config file and which parameters should I increase? ---

Look for ignition.conf in your installation folders. It varies with platform, so I won’t be more specific. (I don’t run Ignition on Windows, fwiw.) This [post](https://inductiveautomation.com/forum/viewtopic.php?f=50&t=14329), while a bit outdated, is still relevant. {G1GC is the default in Java 8.}
