I'm running 2.2.36.1 under Solaris 10 (patched to current) on UltraSPARC. There's plenty of memory, plenty of swap, and plenty of disk, but this is a fairly busy mail server.
Are you sure there is plenty of space on /var/mail/ ? Because that should only show up when the mount point is full.
Also, what is your definition of “plenty”? (I have some index files in the 50MB range, and I am sure there are people with indexes much larger than that).
