Cisco C8500L-8S4X crashed unexpectedly with "Critical process vdaemon

[hardwaremahavikas]

I am using Cisco C8500L-8S4X with SDWAN-image version 17.6.5a in controller mode and recently saw a crash on the router with the output below. I had gone through the datasheet and bug lists unfortunately I did not find any related bug that mentioned about critical process for vdaemon.

System returned to ROM by Critical process vdaemon fault on rp_0_0 (rc=139)
System image file is "bootflash:packages.conf"
Last reload reason: Critical process vdaemon fault on rp_0_0 (rc=139)

Kindly need some assistance to advise what is the possible cause of this error or any possible new bug.

Thank you for your kind assistance.

Just looking over somethings from your info - "rc=139" code provided information doesn't offer details about the specific reason for the vdaemon fault represented by the "rc=139" code. But using the code i found this bug
