zero-length string error ?

Hi !

Error Diagnostic Information

ODBC Error Code = 08S01 (Communication link failure)

Error while executing the query; ERROR: pg_atoi: zero-length string

This is what I get now when trying to update thorugh a form, after power
failure last night. From command line update goes ok.

I'm running a cfml/web-application on linux RH7.3 and PG 7.3.3

Never had this before, what does it mean ?

TIA,

Aarni
