This is very like because you/customer deployed a template of VM that is not supported for SNTC processes and collection.   On installation of the ova it has the full appliance OS, application, and all necessary third party on the ova In deploying it will ask the size of the network that will provide the requirements and automatically configure the ova to that requirement, for SNTC the minimum is the Small (10K devices)  unless the number of devices are higher and you can select the respective matching option   However there is another option that I did not even put here on the chart to avoid confusion of selection , but it called tiny with 40G of hard drive, 2 gig of me and not enough core or processors.   based on the message below your 40 gig hard drive is full.  This happens because not having enough memory and processing power causes the kernel to not process and issues log messages errors, these log messages goes to the syslog and because a full circle if it up into enormous logs.   You cannot do anything on collector now because anything that needs to be done needs to write to the disk even login in.  but it can't because there is no space.  Even if you could recover by deleting those large files ( message and kernel) the problems will reoccur on that cycle..  But to confirm please verify your resource setting and verify if you have a tiny version if so you most definitely need to redeploy but that is the cause of the problem.  If you do not have that version you will still need to redeploy but the reason this occurred is uncertain at this time.         ...

           Total memory is showing less than the required.  So my recommendation is to redeploy to the "small" version of the collector. Because even if you fix it to work temporarily this problem will reoccur with frequency,  I did not see your response of the Vmware ESxi host software version.      I think for  a deployment the only thing you need essentially to export is the credentials and the list of managed devices  then you should be able to redeploy.  Just in case just power off the original redeploy a new image and if needed to return to the old one you can.  If not after the redeploy you can delete it.  the selection of the resources  of the appliance occur on the same file install for all types. export device list : page 8 chapter 3 export credentials: page 2 chapter 6  (is not on the headers but the button is just beside the import one) https://www.cisco.com/c/dam/en/us/support/docs/cloud-systems-management/common-services-platform-collector-cspc/CSPC-User-Guide.pdf       ...

thank you for your detailed Information.   based on the output - You have deployed the tiny version of the collector which is only using for testing ( just a few devices and not ongoing process. so when you add the process for upgrade the box cannot handle it if it was "sort" of working with the tiny version. please let me know what version of Vmware ESxi host you are running and please do the command below and let me know # free -m   if it shows only 2 gig of mem then you do have the tiny version and not enough overall resources to run an official SNTC CSPC Please confirm and let me know. ...
