I use aaf and ferret drb server and one of our indexes is quite large.  
In the case that I need to rebuild it this can take up to several  
minutes.

The problem I have is that it appears that if you have a mongrel cluster  
of 2 or more then if your purge your indexes and restart mongrel that  
simultaneous rebuilds can occur which corrupt each other.

I have been forced to only bring up one mongrel, wait for it to rebuild  
then bring up the other one.

Have I done something wrong in the configuration or is this expected  
behaviour?
