Unable to start application tier due to: kernel BUG : soft lockup CPU#0 stuck for 89s

[GuruGardner]

Guest = Oracle Linux Server release 6.10
Kernel 3.8.13-118.37.1el6uek .x86_64 on an x86_64
Host = Windows 10 Pro N 64 bit
Virtual box version 6.1.16 r140961 (Qt5.6.2)
CPU = Ryzen 7 2700x
1 CPU
8 cores
16 threads
Base memory = 32768mb

Virtual box appliance has Oracle 12.2.9 vision installation. The scenario is I start it up and log in as oracle, able to successfully start the dbase but after submitting the command to start the application tier repeatedly receive the message:
kernel : BUG: soft lockup - CPU stuck for 89s! [java 2123]
BUG: soft - lockup - CPU stuck for 90s! [java 2123]

Have reviewed this forum for possible solutions and also google then tried the following:
- reduced the number of CPUs to 2 then 1 in the settings
- reduced the base memory
- increased the base memory
- ensured that there were no other processes running on the CPU
- turned off home firewall, anti virus
- checked the value of softlockup_panic = 0
- set kernel watchdog_thresh to 40 then 60 (previously 10)

Still getting this issue. Is there anything else I should try? Desperately hoping I don't have to ditch this and start the whole thing again. Have uploaded the log file.

I see you have the VM on a drive 'H'. What kind of drive is that?

You might also like to reduce the CPU count to 2 and the RAM allocation to 8GB. Leave it there unless you know for a fact that the VM needs more: VirtualBox is an app running on the host, so starving the host of resources does not make the VM more stable.

Also, increase graphics RAM to 64MB.

Will this VM have a GUI? If yes then you may want to increase VRAM even more.

Thanks for the response.

Here are the drives:
Storage
1863GB Seagate ST2000DX002-2DV164 (SATA ) 33 °C
1863GB Western Digital WDC WD20EARS-00MVWB0 (SATA ) 32 °C
931GB Seagate ST31000524AS (SATA ) 35 °C
465GB Samsung SSD 970 EVO 500GB (Unknown (SSD))
238GB SAMSUNG MZVLW256HEHP-000L7 (Unknown (SSD))

The H: drive is the Seagate ST31000524AS
Partition 0
Partition ID Disk #2, Partition #0
Disk Letter H:
File System NTFS
Volume Serial Number 4CC8E445
Size 931 GB
Used Space 785 GB (84%)
Free Space 145 GB (16%)

The VM will have a GUI so I will follow your suggestion to increase graphics RAM and also to reduce CPU count and RAM allocation. Will come back as soon as I can on the outcome.

Followed your advice and reduced the CPU count to 2 and the RAM allocation to 8GB. Also, increased graphics RAM to 64MB. Have retried and still having the same issue.

Is there anything else I can try?

Since this is a problem inside the guest OS, you could investigate it like on a physical PC. For example, start with connecting with SSH to the guest and running tail -f /var/log/syslog (*) in a terminal.

(*) I don't know anything about Oracle Linux Server. The example command would work in Debian Linux based systems (e.g. Debian, Ubuntu, Mint), but I think you get the idea ...

@ftho Thanks for the tip will give that a try
