Somethings very wrong. The LDM configuration-file entry on Mlsoserver

> ALLOW   ANY     ^mlsodata\.hao\.ucar\.edu$

should allow the LDM on Mlsodata to successfully request all EXP data-product, 
which it does:

> EXEC    "pqact"
> REQUEST EXP ".*" mlsoserver.mlso.ucar.edu

But inserting a file on Mlsoserver

should cause it to appear in Mlsodata's product-queue, which it doesn't

You should be able to verify this by executing the command "ldmadmin watch" on 
both Mlsoserver and Mlsodata and then pqinsert(1)ing another file on Mlsoserver.

Do the log files on either system indicate a problem?

Data-products are no longer manually removed from the product-queue: the pq(1) 
library module takes care of that automatically.
