Duffa13 Posted March 13, 2015 Share Posted March 13, 2015 Hello everyone! I am having an issue with chunk loaders crashing my server. This is the second time this has happened and I am really hoping someone will be able to help me. Here is my crash-report: http://pastebin.com/3ftbL7KX Thanks in advance!

Discord Moderator plowmanplow Posted March 13, 2015 Discord Moderator Share Posted March 13, 2015 Looks to be more of an issue related to Ender Storage (another ChickenBones mod): java.lang.NullPointerException at codechicken.enderstorage.storage.item.TileEnderChest.reloadStorage(TileEnderChest.java:98) at codechicken.enderstorage.common.TileFrequencyOwner.func_70312_q(TileFrequencyOwner.java:33) The crash report does list a specific location for the ender chest. Possibly something intended to receive the output of a quarry (which loads its own chunks)? You might try removing the quarry and/or chest using MCEdit if the server crashes anytime the chunk is loaded. Duffa13 1 Link to comment Share on other sites More sharing options...
Duffa13 Posted March 13, 2015 Author Share Posted March 13, 2015 I have restored my server via a backup but is there anyway to prevent this issue from happening again? Link to comment Share on other sites More sharing options...
Discord Moderator plowmanplow Posted March 13, 2015 Discord Moderator Share Posted March 13, 2015 It is really dependent on how it happened in the first place. Things you might investigate: Were there any related crashes? When or how often did the server hard-terminate? Has the disk holding the server ever filled up? How are you doing your backups? How often are you doing a world-save? How many concurrent players do you have that warrants having 16G allocated to the server? Link to comment Share on other sites More sharing options...

There was a crash here is the relevant log http://pastebin.com/ugsK5Mxd When or how often did the server hard-terminate? Not sure what this is? Has the disk holding the server ever filled up? Not that I am aware of How are you doing your backups? Backups are run once per 24 hours via a backup script and stored on external ftp backup storage How often are you doing a world-save? World save every 10 minutes How many concurrent players do you have that warrants having 16G allocated to the server? We don't really have that many players maybe like 5-15 but I have a dedicated server and plenty of RAM available so it should be no issue dedicating this much RAM?

Discord Moderator plowmanplow Posted March 13, 2015 Discord Moderator Share Posted March 13, 2015 Believe it or not, allocating more RAM to the server (or client, for that matter) than one needs is usually a bad idea. All the unnecessary RAM can cause the garbage collector to work harder that it should at times resulting in funky lag spikes and odd behavior. It's usually a good idea to start low and work your way up as needed. By hard-terminate, I just mean hang/crash/improper shutdown. Basically, instances where the internal server logic processes hung and the data on persistent storage (i.e. hard drive) can become inconsistent.

Duffa13 Posted March 14, 2015 Author Share Posted March 14, 2015 So I am still unsure what I can do to prevent these issues? Link to comment Share on other sites More sharing options...
