I know of 1 example where coke formed due to di-olefin polymerization of naphtha on the shell side causing the bundle to swell significantly. However, the tubes did not fail as a result. Therefore, it may be possible in an extreme case but is seems unlikely. You would likely need a shut-in condition of the resid side with heat input (HKGO) still flowing for a long time to cause a tube failure.
