Wildfly server 10 Memory leak on deployment or undeployment - wildfly-10

I am using wildfly server 10 as well as wildfly server 17. I am facing the memory leak issue multiple times when I am deploying and undeploying the applications.
My server is install on Ubuntu 18.04 with 4 GB Memory / 80 GB Disk / BLR1 - Ubuntu 18.04 (LTS) x64 configuration.
Whenever I deploy my application war file 2/3 time I am getting this error. After restarting the wildfly server I am able to deploy or ready for deployment or my war file deployed successfully on server.
Hence I want to know why I am facing this type of issue if I have a better configuration?
How can fix this?
How can I avoid this type of issue?
Is wildfly server updation is the solution then Why I am facing the same issue in wildfly server 17?
Thank Prasad.

Solved the issue by deleting oracle and java instances because i have install jdk 1.7 and oracle developer 10g contains jdk 1.4,so there is an issue in java versions..because of that when i run weblogic.jar file,it gives an error

How to install mod_ssl on windows server 2008 64bits

We manage our own VM Windows Server 2008 R2 STD 64 bits which is use as a web server.
APACHE httpd-2.2.22-win32-x86-no_ssl is install on it since the beggining cause this was the only self install file (MSI) that we found on Apache web site.
I now need to install an SSL Certificate. I ran into a couple of forum without getting the exact solution method to my situation.
I use OpenSSL to create our own Self Sign Certificate on purpose of this installation. The issue is where can I find mod_ssl module that is missing ? I have no experience yet (but it's never too late to get a start) with compiling binaries and where can I get some safe binaries for this module if order to continue in configuring this dawn SSL Certificate ? :)
On the same machine i'm also running :
php-5.3.13-Win32-VC9-x86
mysql-5.5.24-winx64
FileZilla_Server-0_9_41
hMailServer
Finally, I just took it (mod_ssl.so) from my dev. server under an WAMP solution. I'd uncomment the ssl_module line into httpd.conf as suppose and all Works fine on my production server with this module.

Installation crashes. SQL Server 2008 r2 Express

I'm trying to install SQL Server 2008 R2 express on my fresh win 7 ultimate x64 install. Every time the installation starts, it crashes with the following message:
Description:

Did anyone had similar problem? how did you solve?
So here are some ideas to try if they help. First, I assume that you're installing the 64bit version of SQL Express? Also, the faulting module is a .NET component, so maybe try repairing .NET 2.0? Finally, I'm not sure this would work, but as a last-ditch effort, you could reboot to safe mode and try the installation from there. I know these are just shots-in-the-dark, but if 300 billion web pages don't have the answer, then maybe some random tests might get lucky.
In my experience SQL express installs tend to crash (well over the past 5 years anyway) when you install direct from the web. I would allways recommend downloading the complete install package, then runing it from a local folder. Everytime the direct web install has crashed for me (probably around a dozen time now accross various versions), downloading the full install and then running it locally has lead to a clean install.
