Router in reboot loop??

[GREGORY GEE]

I tried to upgrade my 2600 from 12.0(7)T IPonly to IPplus, but it complained that I didn't have enough memory. When it first tried to start the IPplus load, I saw some brief message about heap/change/10%... Since it did not load, I went back into rommon and tftp the original load I had before. But now it says that I don't have enough memory for that load either. Did the IPPLUS load change something so that the IPONLY load won't load. I even tried loading a 11.3 loadm but that just spewed errors as well. Someone mentioned that it might be the shared memory allocation was changed. Is it posible to reset the shared memory setting?

Thanks,

Greg

I had a similar issue with a 1700 in a reboot loop, running 12.0(7)T. The code is now deferred for the 1700, do to memory issue. See below. Although reason for deferral had nothing to do with what was going on for us, there may have been some other memory issues going on in the background. Upgrading to different version resolved issue. Try different version and not just different feature set.

I have recently upgraded a 2600 series router, and had similar messages (not enough memory).

When I changed to config register to 0x2101, the upgrade flew in.

Thanks
