commlog destination in Solaris

Hi,
We're having problems with connection failures from Informatica to GP/PG. there's nothing in the GP/PG log.
We've turned on the commlog trace in the odbc settings.
Can someone tell me where I can find the log location?
We're running PsqlODBC 8.0.4 on solaris 10 sparc 64bit.

Our odbc.ini file
[GreenplumProd_Write]
Driver=/infa/GreenPlum/greenplum-connectivity/drivers/odbc/psqlodbc-08.02.0500/datadirect-52_32/psqlodbcw.so
