WildFly 18 deployment fails for (.ear) deployment file size more than 2GB

I am trying to deploy the EAR file which has a size of more than 2GB in the WildFly 18 domain master server using jboss-cli.bat.
deploy deployment.ear --server-groups=server-group-app
The outcome of the deploy command shows success but the content file creates inside the domain/data/[hexcode] folder after deploy command has 0KB size.
Size of the content file becomes 0kb after deployment
And the same EAR file when I try to deploy using master management console running on 9990 port, it also deploys successfully and the content file creates inside domain/data/[hexcode] folder has actual deployment size which is more than 2GB
Size of content file same as EAR file after deployment through management console
But it gives the following error on slave server startup in slave's host-controller.log file
2021-03-12 15:57:15,143 ERROR [org.jboss.as.controller.management-operation] (Host Controller Service Threads - 4) WFLYCTL0013: Operation ("add") failed - address: ([

So, is there a way with which I'll be able to deploy my EAR deployment file which has a size of more than 2GB in WildFly 18 domain master server using jboss-cli.bat?
Thanks in advance...

Unable to Launch the Neo4j Console App After Upgrade to macOS Big Sur

Yesterday, I upgraded my iMac to macOS Big Sur. When I attempted to launch the Neo4j Console app in Terminal, it returned a series of errors. I was running 3.5.20 of the Community Server.
I thought I could resolve these errors by installing the latest version of the Community Server. I downloaded and installed version 3.5.24. When I attempted to launch the 3.5.24 database, it returned the following errors, which are similar to those version 3.5.20 produced.

The database was running just fine before the upgrade. Has anyone experienced this error? Any ideas on how to get the Community Server database working again?
Thanks in advance for your help.

Do you have JAAS configuration file? If you do, then you probably have old format of "initiate" section - com.sun.security.jgss.initiate, note that it's missing ".krb5". It should be com.sun.security.jgss.krb5.initiate.
Or maybe the path to configuration file is incorrect in your server startup command line.

Spark not able to access hbase but able to access with java code

I am using spark 1.3.0 with hbase 1.0. After one week. Hbase run successful with java code. But when using Hbase with spark giving error. I also check with hbase shell is work fine. This errors occurred after long time otherwise work fine with spark also.

But error occurred first when try to put something into hbase.
Second error when try to read from hbase.

The problem is with the HBaese Table locking. The is in hung up or limbo state.
There are some suggested solutions.
Run following commands:
hbase hbck -fix
HMaster reboot
If above solution fails
Restart the Master
If above solution fails
Restart The Zookeeper
If everything fails
Restart the cluster
