In the use of Web-iou test, accidentally found a test topology, about 20 devices, there are 6 devices can not save the configuration, save the time also appeared error, error content as follows:


*jun 05:49:50.842:%sys-2-nv_bad_ptr:bad NVRAM pointer. NV Header values are, nv:0x0x10fad788 textbase:0x0xab736714. textsize:2542 magic:0xabcd. checksum:0xa495. System_ve rsion:3840. textptr:0x0xab737102 v1_ptr:0x0x0. priv:0x0xab737108

*jun 05:49:50.842:%sys-4-nv_block_initfail:unable to initialize the geometry of NVRAM


To report the wrong content at the beginning of the device has also appeared, and the device can not view the NVRAM file directory, and error, as follows


Router#dir NVRAM:
%error opening nvram:/ (Unknown error 0)


The phenomenon is more bizarre, the same iOS, initial configuration, some devices will not appear the problem, can be saved, the Internet search, some people think it is software bug, tried to replace the iOS file, replace the initial configuration file, there is no way to solve. Finally re-establish the experimental topology, iOS, configuration and the original is exactly the same, the problem is not reproduced, all devices can be saved normally.

So, for the time being, the problem is a software bug, as far as the underlying causes are unknown.
