Re: (ITS#4240) back-meta loses "connection" with remote backend

[pfnguyen@hanhuy.com]

I don't see how it's a problem with the remote server, but anyway, I 
finally got around to capturing a loglevel 261 log (of a connection that 
works and one that does not).  I tried stepping through the code in gdb 
but I couldn't really make heads or tails of what was going on.

Anyway, the log is here:
