Using Index for causes timeout Amanda 2.4.1p1

[Richard Eames]

When I turn indexing on for partitions with large numbers of files the dump of those 
partitions times out. However, without indexing the dump process works fine. I've 
tried bumping up the data timeout but this has no affect.  The problem appears to be 
independent of client operating system (happens under AIX and Solaris for Intel). Note 
I'm using an AIX 4 box as the server.  Any ideas ?
