cscope errors: E262: error reading cscope connection 0

[Eran Borovik]

Hi all,
I use vim as my main editor for programming and I'm enjoying it to no end. For tags, I use ctags (Exuberant Ctags 5.8) and cscope (version 15.7a).
My problem is that occassionally when I do a cscope search using "cs find" I get the cscope error: E262: error reading cscope connection 0
Resetting cscope temporary solves this until it happens again.

Further information:
I configure vim to always have 3 open cscope databases: For the Linux kernel, for glibc, and For my project.
vim is configured to have the same corresponding ctags databases for the same projects.
