socket never became readable

[Fred Moyer]

Hi,

I've been encountering the following error message in my application 
server logs on an infrequent basis:

MogileFS::Backend: socket never became readable at 
/home/app_user/perl/lib/site_perl/5.8.6/i686-linux/MogileFS.pm line 167

Perlbal and MogileFS daemons are running on a front end proxy server, and 
this message occurs occassionally in the application server logs during 
re-proxy handling.  On the client facing server there 4 perlbal daemons,
4 mogstored daemons running at idle and about 2 dozen mogilefsd daemons.

Any clues on the next step in debugging this problem are appreciated, 
chances are I'm missing something obvious here as I am a relative newcomer 
to re-proxying in production.

Thanks,

- Fred
