The problem is both of them randomly will just freeze, and I cant SSH to them anymore. Checking the console shows the following:

vXR 01

If I hit ENTER a couple times form console, after about 1-10 min, the system will come back to life and I can log in, then SSH will work again. 

I ran the following to see what is going on

I can see that `/misc/disk1` partition is getting filled up, I ran the following to see what are the biggest files

What is odd, sometimes when a vXR freezes, then I unfreeze it, admin, run, and check `df -H` the partition is no where near what the terminal is complaining about. So I assume there is some mechanism that is cleaning up after itself, and some times it cant?
Some times I even see these error messages, and at this point I just need to reload (reboot) the vXR.

 

 

[22048.168007] BUG: soft lockup - CPU#1 stuck for 22s! [ixdb_gc:8898]
[22048.185007] BUG: soft lockup - CPU#2 stuck for 22s! [vpe_main:8156]

 

Its not clear to me what is filling up the partition or if its related to why the vXR freezes. I can only assume its a log that is filling up from my poor configurations. 
How can I figure out what is filling up? I COULD build a cronjob to clean up whatever fill is filling up, but what is the correct way to fix this? 
Anyone have any ideas

EDIT: 
The workaround I found was to delete the default-sdr--2.20220706-184037.core.RP.lxcdump.tar.lz4 file first. It was huge.
Then I noticed many more `default-dr--*.lz4` files were being created. So I deleted the glob, now `df -H` is back to normal. I THINK these files are made by the XR to pass off to support when there is a problem, I see a message about them after I reboot the system. Is there a way to stop the system from creating these files?

XRV is very high resource required image for the Lab, what kind of compute you have ?

if you looking only do some labs, I go back to 6.X image and they work  as expected (until you see any specific reason to use 7.3 code)

I don't understand what I am supposed to be looking at from the link you shared. Is it resource requirements? If so its not clear on what the requirements are for a vXR 7.3.1 are from that link.

I am currently running GNS as a vmware appliance. I have given the appliance a lot of resources (30 CPU cores, and 128 GB of memory) and I can give more as the guest is running on very large hosts. However these are shares and the vm never gets close to using all the resources. Memory and CPU stay at around 30-40% for the GNS3 appliance. Re: Disk space the gns3 guest has 500GB to use which is not being close to being used. The GNS3 configuration for each vXR is using 1vCPU and 17000MB of ram. These settings are the default and what were recommended to be used by guides on the internet. 

Therefore I don't believe this is a CPU or RAM issue. Its obvious the partition is filling up from what I shared above, and its getting filled up by those .lz4 files. The vXR's work perfectly fine with no problems, until that partition gets filled.

Finally, I must use vXR 7.3.1 image, its a requirement for the project I am on. Cannot go down to a earlier version.


Again, what are those files for? And how can I stop the system from building them or clean them up?

 

BUG: soft lockup - CPU#1 stuck for

the error above indicates that the watchdog/nmi process is waiting for the CPU to respond. either the cpu is not responding or the kernel locked up, when this happens the device will write a core file to the disk and reload.

Those core files indicate a crash, you can delete them via the following command

admin

delete harddisk:*.core*

delete harddisk:*.lz4
