Serversync Version:

3.5.1

Minecraft Version:

1.12.2

Issue:

After actual sync, server starting to spam errors in console and log file. Sync still works but very slow (~15 minutes for whole syncing instead of 2 minutes as usual) This happens when i syncing 2+ times. Problem happens without arguments and with java -jar -Xms256m -Xmx2g serversync-3.5.1.jar server too

Console repeat messages:

Exception in thread "Log Saving" java.lang.OutOfMemoryError: Java heap space
Exception in thread "Log Saving" Exception in thread "Log Saving" java.lang.OutOfMemoryError: Java heap space

Also, when syncing client and server process takes about ~4.5 Gb of RAM

How large is the combined size of the directories being synced?

Feels like there is probably some leaking going on during the file IO

About 350 mb.

Closing this as v4 has had significant changes in IO, feel free to reopen if the issue persists
