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