Re: {bb} unable to contact BBD

[Ben Pitzer <bpitzer@gmail.com>]

Okay, well, I've got the fping.sh problem resolved, but the overall
problem remains:

Wed Mar  9 12:33:06 2005 bbd CONNECTION TO my-bb-server.domain.com TIMED OUT...
Wed Mar  9 12:33:06 2005 bbd CAN'T CONNECT TO bbd SERVER @
my-bb-server.domain.com

The tcp_time_wait_interval is at 30000, so that's not causing it,
either.  I'm not sure about the tmpfs directories, but given the
scripts that I have to run, I can't really spare the memory for that
particular solution.  I can look into the bbproxy piece, but I'm not
sure if that's something I can implement or not.

Any more ideas would be greatly appreciated.

Regards,
Ben Pitzer
