vim stuck on write

[ping song]

Experts:

I need some help here please...

I have a on-going projects that I'm working on with vim. I never saw this until today...

whenever I change a tcl file and :write 

the vim got stuck...for ever.

no cpu spike, gnu screen/tmux works fine where vim is running inside.

no file permission issue - if I set ft=txt and write, there won't be any problem...

so I turned on vim debug (-V4).

it looks I'm stucking at:

vim-misc 1.16.1: Executing external command using system() function: sh -c '(/usr/bin/ctags-exuberant --fields=+l --c-kinds=+p --c++-kinds=+p --sort=no -f- '\''--language-force=tcl'\'' '\''/home/ping/Dropbox/lin

g-backup/crtc/crtc.abc'\'') 1>'\''/tmp/ve6IXR8/15'\'' 2>'\''/tmp/ve6IXR8/16'\'''

shell to execute: "(sh -c '(/usr/bin/ctags-exuberant --fields=+l --c-kinds=+p --c++-kinds=+p --sort=no -f- '\''--language-force=tcl'\'' '\''/home/ping/Dropbox/linux-config-backup/crtc/crtc.abc'\'') 1>'\'

6IXR8/15'\'' 2>'\''/tmp/ve6IXR8/16'\''') >/tmp/ve6IXR8/17 2>&1"

so it seems to be related to this vim-misc plugin...but I still doubt it -- I'm not sure I can uninstall it since a lot of plug-ins I'm sure depend on it - autotag seems one.

anyone please shed some light here?

thanks.

regards

If the cpu is not doing anything, it sounds like one of the
sub-processes is waiting on input.
