Hello, After upgrading to Wicket 8.6.1 we started seeing periodical OOMs in logs like below. I'm not 100% sure that it's due to Wicket, but we didn't change containers parameters and etc - so at least it's quite suspicious. Our startup flags: -XX:+PerfDisableSharedMem -Xmx4G -Xms4G -XX:MaxDirectMemorySize=4G -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/app/runtime/heapdump.bin
Btw, except these exceptions in logs - no other negative effects (at least we didn't reveal so far). If you have ideas - I will really appreciate. java.lang.OutOfMemoryError: Direct buffer memory at java.nio.Bits.reserveMemory(Bits.java:666) at java.nio.DirectByteBuffer.<init>(DirectByteBuffer.java:123) at java.nio.ByteBuffer.allocateDirect(ByteBuffer.java:311) at sun.nio.ch.Util.getTemporaryDirectBuffer(Util.java:241) at sun.nio.ch.IOUtil.write(IOUtil.java:58) at sun.nio.ch.FileChannelImpl.writeInternal(FileChannelImpl.java:778) at sun.nio.ch.FileChannelImpl.write(FileChannelImpl.java:764) at org.apache.wicket.pageStore.DiskDataStore$SessionEntry.savePage(DiskDataStore.java:352) at org.apache.wicket.pageStore.DiskDataStore.storeData(DiskDataStore.java:185) at org.apache.wicket.pageStore.AsynchronousDataStore.storeData(AsynchronousDataStore.java:217) at org.apache.wicket.pageStore.AbstractPageStore.storePageData(AbstractPageStore.java:119) at org.apache.wicket.pageStore.DefaultPageStore.storePage(DefaultPageStore.java:66) Thanks, Ilya --------------------------------------------- Orienteer(http://orienteer.org) - open source Business Application Platform --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
