Sonar 7.3 startup hangs / log says: Cleaning or creating temp directory

Hello Sonar Community,
I am using Sonar 7.3 on Windows. It has worked fine on this machine in the past. I had to reboot the machine. Now when I start Sonar 7.3 a single Java.exe process starts running and the “sonar.log” file says “Cleaning or creating temp directory” It has been like this for an hour. Java process is still using CPU cycles, but the log says nothing more. None of the other Sonar Java.exe processes are starting either.

Q: Can I just DELETE the entire SONAR TEMP directory? Maybe it’s having a hard time cleaning it. Maybe let it rebuild again?

“Sonar.log” says as follows

–> Wrapper Started as Service
Launching a JVM…
Wrapper (Version 3.2.3) http://wrapper.tanukisoftware.org

2019.02.25 13:11:05 INFO app[o.s.a.AppFileSystem] Cleaning or creating temp directory D:\BUILD_SYSTEM\sonarqube-7.3\temp

Following from above.
Sonar 7.3 finally started - it took 30 minutes (not an hour, sorry – from above)
It just took that long.
Unsure why.

Anyway - no need to respond. It’s working now.
