SonarQube is getting stopped after running for some time - sonarqube

Earlier I was able to run SonarQube without any problem. But recently after executing ./sonar.sh start script a SonarQube.pid file is being generated and until the time the file is present. Sonar is up but after few secs the file is getting deleted thus making Sonar going down.
I couldn't understand why the problem is occurring suddenly now. How to resolve this issue.

On the SonarQube server, check the log files and identify the root cause. If it was installed to the default directory in C:, The location of the log files would be : C:\Program files\sonarqube7.2\logs

Unable to save output from Rscripts in system directory using Devops Pipeline

I am running Rscripts on a self hosted Devops agent. My Windows agent is able to access the system's directory where its hosted. Below is the directory structure for my code
Agent loc. : F:/agent
Source Code : F:/agent/deployment/projects/project1/sourcecode
DWH _dump : F:/agent/deployment/DWH_dump/2021/
Output loca. : F:/agent/deployment/projects/project1/output_data/2021
The agent is using CMD in the devops pipeline to trigger R from the system and use the libraries from the system directory.
Problem statement: I am unable to save the output from my Rscript in to the Output Loca. directory. It give an error as Probable reason: permission denied error by pointing to that directory.
Output File Format: file_name.rds but same issue happens even for a csv file.
Command leading to failure: saverds(paste0(Output loca.,"/",file_name.rds))
Workaround : However I found a workaround, tried to save the scripts at the Source Code directory and then save the same files at the Output Loca. directory. This works perfectly fine but costs me 2 extra hours of run time because I have to save all intermediatory files and delete them in the end. Keeping the intermediatory files in memory eats up my RAM.
I have not opened that directory anywhere in the machine. Only open application in my explorer is my browser where the pipeline is running. I spent hours to figure out the reason but no success. Even I checked the system Path to see whether I have mentioned that directory over there and its not present.
When I run the same script directly, on the machine using Rstudio, I do not have any issues with saving the file at any directory.
Spent 2 full days already. Any pointers to figure out the root cause can save me few hours of runtime.
Solution was to set the Azure Pipeline Agent services in Windows to run with Admin Credentials. The agent was not configured as an admin during creation and so after enabling it with my userid which has admin access on the VM, the pipelines were able to save files without any troubles.
Feels great, saved few hours of run time!
I was able to achieve this by following this post.

Build Failed from Dev to Staging using TFS Release management

I am trying to build a project from dev to staging environment, what all i did was just to merge the changes in dev to staging and trigger a build. but the build got failed even tried multiple times.
Below is the log file shared in google drive. there are no errors mentioned in the log file. Can anyone help me solve this problem.
https://drive.google.com/open?id=0B85ZmWDiKYHRVmN4MlMxc0ZEd28
I found a error in the log file in the release management, which says that "access denied for appsettings.config" file. I did remove the read only on the folder in the server and it worked. I am not sure of this fix properly, but it did work for me.
Thanks.

TFS Build Error Path already mapped to another workspace Occuring even after deleting cache file

Firstly I read through many existing threads and followed the instructions there
Here
Here
Here
Here
Here
Here
Almost all the above threads asked me to delete the cache file. I went into the machine and deleted the cache file. I even edited the cache file (XML file named version config) but still it gets overwritten
But still even after that I am seeing the same issue.
The build agent has got dynamic $SourceDir as value
What else can I do to fix this? Please Help.
I tried doing tf workspaces but it simply keeps saying that "Unable to determine the source control server"
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\TeamBuild\Microsoft.TeamFoundation.Build.targets (838): Unable to create the workspace 'NVM1756PDV_105_7' due to a mapping conflict. You may need to manually delete an old workspace. You can get a list of workspaces on a computer with the command 'tf workspaces /computer:%COMPUTERNAME%'.
Details: The path C:\Builds\7\Common_Security\cloud\src is already mapped in workspace NVM1756PDV_104_7.
Run the tf workspace /delete NVM1756PDV_104_7 command to correct this error.
Try using TFS Sidekicks to delete the workspace using the Workspace Sidekick.

Jdeveloper 11gR1: java.lang.IllegalStateException when opening project

I installed 11.1.1.5 just now, and am getting this error every time I try to open a project or a directory in a project, I get the following error:
java.lang.IllegalStateException: Timer already cancelled.
And it doesn't display the files.
To exclude any other factors I did a fresh install in a new Ubuntu VM image - same problem.
I'm really at my wit's end.
I solved the problem by deleting all local projects and checking out the source code again.
