Failed to create a child event loop minecraft что делать
Обновлено: 04.07.2024
I am getting errors like "failed to create a child event loop/failed to open a new selector/Too many open files" when there are 30 or more concurrent requests. How to solve the above errors? Am I doing anything wrong? I am using Spring boot and Java cassandra driver. Below is the connection file:
Below is the ConnectionBean file which I used in Connection file:
Below is the class from where ConnectionBean variables are initialized :
And finally, below is the class through which I am querying cassandra data:
May I know form where to check database connection limit? I also tried java-cassandra driver PoolingOptions with MaxQueueSize = 4096 and MaxRequestsPerConnection = 32768. Thanks.Minecraft Forums

A detailed walkthrough of the error, its code path and all known details is as follows:

Minecraft 1.13 crashing upon "saving world" text. Error "Unable to create child event loop"
Now before anyone says to look at some certain FAQs/posts; I did. Any that anyone has redirected others with this same, particular problem, but to no avail, has helped me. OR, the problem I have, no one else has.
I recently fresh updated to 1.13 and tried to go into one of my screenshot worlds. (To note, I am the Java version user due to having Win7) I made sure it was optimized. Clicked to go on in, and was met with the error after I saw "saving world" and crashed. Opened the game back up, did a fresh world made. Tried again. Same result.
" The game crashed whilst mouseclicked event handler
Error: java.lang.IllegalStateException: failed to create a child event loop "
So I went online to see if anyone else has these problems and their fixes. Many have, but different results for each person. I have tried, for hours on end, to literally fix this dumb error. Looked on posts, the reddit, videos-- nothing. I even have the crash log and will upload the log to view here as well.
I really wish to play the current update since it seemed great enough to make a comeback to the game after about almost a year or so without playing.

If getConnection() is being invoked for every request, you are creating a new Cluster instance each time.
This is discouraged because one connection is created between your client and a C* node for each Cluster instance, and for each Session a connection pool of at least one connection is created for each C* node.
If you are not closing your Cluster instances after a request completes, these connections will remain open. After a number of requests, you'll have so many connections open that you will run out of file descriptors in your OS.
To resolve this issue, create only one Cluster and Session instance and reuse it between requests. This strategy is outlined in 4 simple rules when using the DataStax drivers for Cassandra:

Hello. For a month and so I have been encountering an error that I have been trying to resolve, but my methods never work. I have encountered a java.lang.IllegalStateException: failed to create a child event loop
In my guess, this error occurs when an Antivirus, Java, or any software is blocking the game. When I first had the error, it DID show what my game was going through Mojira Issue MC-34749 , where it was blocked by an antivirus, so I uninstalled McAffe , but it Didn't Work! The only difference is that the crash screen doesn't encounter Mojira, and here is the latest crash screen I had when trying to run minecraft was this:

I have tried many methods, but failed. Below lists the methods I tried to fix my MC in chronological order:
So when I try to play Minecraft Multiplayer , I get this screen that says:
Failed to Connect to the Server
Java.Lang.NullPointer.Exception:Group
Playing one of my Singleplayer worlds would crash and say the same crash log like the one above.
If you find any suggestion, please comment. And if it works, thank you so much!

(This thread will be edited if the issue/exception is resolved, or if there were mistakes to viewers, or I will update crash screen and detail in the future)
