I have a router 837. It runs 12.4(2)T. I've got a strange problem.
When I enable by remote NAT feature on ethernet0 and dialer 0 I get this error message
%Malloc fail re_allocate_memory ../inspect/re_regexp.c 141
% PDL Error : Failed to compile regexp File : rtsp.pdl Line : 113 : (regexp store insensitive ^^^^^^^
% NBAR Error : Activation failed due to insufficient dynamic memory % NBAR ERROR: due to memory problem, parsing stopped % NBAR Error : Activation failed due to insufficient dynamic memory
From that point on I can not see running-config any more and I can not save it as well:it said "not enough space on the device". Moreover, even if I couldn't see the startup-config I did configure line vty 0 4 to match username and password against local database, I did specify the method wanted and also a local password (never used by "login local" method) but the only thing obtained at the next boot was "login". I found it out being 1000 miles far from the router :-(
So I looked for NBAR but it didn't help me. I had a look to system filesystem and I saw which files are stored on it but I wasn't able to see the size. Moreover is there a way to delete some file not really needed to have more space on file system "system"? The problem is there because I can do the command "more" over whichever file I want (startup-configon NVRAM, the IOS too on flash !) but running-config.
