C9300X member switch crashes very often pointing to sif_mgr fault. Reload reason "Critical process sif_mgr fault on rp_0_0 (rc=139)"
Upon loading 17.12.2 XE that is bundled with bootloader version 17.12.1r[FC2], certain 9300X seems to exhibit the crash randomly.
Workaround – Load 17.13.1 XE (this will also upgrade the rommon version that has the fix), followed by loading 17.12.2 image (rommon will not be downgraded) The fix is already committed to the 17.13.1 release which is available on CCO and also committed to the upcoming 17.12.3 release.
