Online V5, ESQL/C, fork() & sqldetach()

I am writing some code in ESQL/C that includes a call to fork(). What I have found in the ESQL/C Programmer's Manual tells me to call sqldetach() in the son-process to open a new DB connection based on the previous connection. The manual adds nothing to this... I do a start database in the son-process after the call to sqldetach(). The other process continues processing other statements concurrently. What happens is that after some ESQL processing in background I get syntax erros in the same statements that were successfull before. I get error (-201) (OPEN CURSOR) ??? I would like to know if someone has been through the same problems.
