Error saying router cant load IOS from flash but, boots fine anyway???

Question

I get this error upon bootup of my 3640 router.
"%SYS-3-IMAGE_TOO_BIG: 'flash:c3640-is-mz.122-34.bin' is too large for available memory (10590520 bytes).boot
of "c3640-is-mz.122-34.bin" using boot helper "flash:c3640-is-mz.122-34.bin" failed
error returned: File read failed -- Not enough space
loadprog: error - on file open
boot: cannot load "c3640-is-mz.122-34.bin"
I have this boot statement:
boot system flash c3640-is-mz.122-34.bin
Here's what my show flash looks like:
System flash directory:
File Length Name/status
1 11336892 c3640-is-mz.122-34.bin
[11336956 bytes used, 4915968 available, 16252924 total]
16384K bytes of processor board System flash (Read/Write)
Like I said, router boots fine but what does this error mean?
*I also get this upon boot*
Smart Init is disabled. IOMEM set to: 10
Using iomem percentage: 10

Answer 1

thank you sundar, I've loaded IOS version c3640-is-mz.121-27b.bin and the router booted up fine with the previous errors.
However...........upon bootup the router is trying to load "call rsvp-sync" and "dial-peer cor custom"

How do I stop this???
Upon bootup I receive this message too.

Does the router still think 12.2 is in their somewhere?
Is that because I have this boot statement?
boot system flash c3640-is-mz.121-27b.bin
