Why does this not work in the latest otp

[Thomas James Malone]

If I use the module I have included as an attachement and run the  
following code in R13B01,

db_dis:new(database, remote@REDACTED).
db_dis:write(tom, london, database, remote@REDACTED).
db_dis:write(stuart, london, database, remote@REDACTED).
db_dis:match(tom, database, remote@REDACTED).


=ERROR REPORT==== 24-Jun-2009::15:13:11 ===
'local@REDACTED' got a corrupted external term from 'remote@REDACTED' on  
distribution channel 5571
<<...,106>>
ATOM_CACHE_REF translations: 0='local@REDACTED', 1=''
timeout

In R12B-5 if  run the same code I get my expected response of []

what am I missing.

thanks in advance

Tom
