Hi all, I have been trying to run updates on our 6506 VSS using the ISSU method. Everything went smoothly until running the issu loadversion command to boot the standby chassis to the new version. Now the standby is stuck in a bootloop, each time with the following errors:
*Feb 19 23:20:15.074: %PFREDUN-SW1_SP-4-PHYSMEM_MISMATCH: Asymmetrical redundant configuration: Active SP has (1048576/65536K) memory, Standby has (1048576/8192K).

The only way to get out of the bootloop is to wait for the rollback timer to kick in (hopefully, haven't waited that long yet) or manually reset the chassis.
As far as I know, the hardware of both chassis are identical.
We are trying to update from s72033-adventerprisek9_wan-mz.122-33.SXI3.bin to the modular variant of the same IOS version.
Any ideas as to what's going wrong?
