java.lang.OutOfMemoryError: Java heap space

[Sirfrancis18]

my library is quite big and now tmm doesn't work anymore. when starting the docker it shows the following error
java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:3236) at java.io.ByteArrayOutputStream.grow(ByteArrayOutputStream.java:118) at java.io.ByteArrayOutputStream.ensureCapacity(ByteArrayOutputStream.java:93) at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:153) at java.util.zip.DeflaterOutputStream.deflate(DeflaterOutputStream.java:253) at java.util.zip.DeflaterOutputStream.write(DeflaterOutputStream.java:211) at com.sun.nio.zipfs.ZipFileSystem$EntryOutputStream.write(ZipFileSystem.java:1579) at java.nio.file.Files.copy(Files.java:2909) at java.nio.file.Files.copy(Files.java:3027) at java.nio.file.CopyMoveHelper.copyToForeignTarget(CopyMoveHelper.java:126) at java.nio.file.Files.copy(Files.java:1277) at org.tinymediamanager.core.Utils.lambda$createZip$1(Utils.java:1445) at org.tinymediamanager.core.Utils$$Lambda$22/1480476051.accept(Unknown Source) at java.util.stream.ForEachOps$ForEachOp$OfRef.accept(ForEachOps.java:183) at java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:193) at java.util.Iterator.forEachRemaining(Iterator.java:116) at java.util.Spliterators$IteratorSpliterator.forEachRemaining(Spliterators.java:1801) at java.util.stream.AbstractPipeline.copyInto(AbstractPipeline.java:482) at java.util.stream.AbstractPipeline.wrapAndCopyInto(AbstractPipeline.java:472) at java.util.stream.ForEachOps$ForEachOp.evaluateSequential(ForEachOps.java:150) at java.util.stream.ForEachOps$ForEachOp$OfRef.evaluateSequential(ForEachOps.java:173) at java.util.stream.AbstractPipeline.evaluate(AbstractPipeline.java:234) at java.util.stream.ReferencePipeline.forEach(ReferencePipeline.java:485) at org.tinymediamanager.core.Utils.createZip(Utils.java:1434) at org.tinymediamanager.core.Utils.createBackupFile(Utils.java:1158) at org.tinymediamanager.core.Utils.createBackupFile(Utils.java:1134) at org.tinymediamanager.TinyMediaManager$1.doStartupTasks(TinyMediaManager.java:450) at org.tinymediamanager.TinyMediaManager$1.run(TinyMediaManager.java:183) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:311) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:758) at java.awt.EventQueue.access$500(EventQueue.java:97) at java.awt.EventQueue$3.run(EventQueue.java:709)

I ran into the same issue with mine. I found the following page. Read the v3 section. Creating the extra.txt file worked for me. depending on the size of your library you might need to increase the memory size (their example shows 1gb - 1024m).

Hope that helps you.
