FreeBSD -bench error on minimalist system

[erk]

I am in the process of making a minimal (64MB)FreeBSD image for a diskless PXEboot folding farm. I have almost got it going, but I have probably missed some critical library and -bench fails with the following error:

farm1.root # ./foldtrajlite -bench
One moment, opening rotamer library...
Predicting secondary structure and generating trajectory distribution...


Error Number -70, 90621
Reading File

/var/tmp/tmp_eJDpJ5_2095_523.fpt
0 8
file4readAllLow


Error Number -60, 91102
Opening File
dfile4...()



The /var/tmp dir exists and is world writable. I did a ldd on foldtrajlite which gave the following dependencies that I made sure were copied across:

foldtrajlite:
libm.so.2 => /usr/lib/libm.so.2 (0x2842d000)
libncurses.so.5 => /usr/lib/libncurses.so.5 (0x28448000)
libc_r.so.4 => /usr/lib/libc_r.so.4 (0x28489000)

Can anyone suggest a library that I might have forgotten to copy across?

Here is my listing of the minimalist /usr/lib:

I also get a similar error trying to fold after the completion of gen 0 I guess it's in the writing/upload stage.

When I first set up my diskless system I was using the default setup which had a 1MB Ramdisk for the /tmp directory. Folding writes 8MBs+ to that directory. I ended up putting the /tmp directory on my NFS server.

One of the two versions of the linux client uses a different libncurses.so than the other one, when I have tried to run that the error message said that it was missing that particular file.

does the named file exist? How much free space is in /var/tmp?

/var/tmp has 16MB free. The file name did exist, it was only about 4MB long. I have just solved the problem by taking someone elses tested version of a FreeBSD 4.8 based diskless workstation system, and copying it to a 64MB RAM based drive image. Because of extra libraries I had to NFS mount a DF client directory for each server in the diskless farm to save some space, this worked well as it stops falling back to gen 0 after a reboot.

The diskless image I started from was for a WiFi Freebsd router:
