odbc otl lockup in rlogon

I am using he latest otl header (v 4.0.159) with the latest odbc library. I have a heavily multi-threaded application using otl to do many simultaneous read/writes on my postgres database.

Randomly, I will see the rlogon function lockup on the SQLSetEnvAttr function call.

When I set Threading=3 or Threading=1, it locks up more often.
Also, I have compiled odbc and postgres for multi-threaded use. I also call the otl_initialize(1), so that otl lets the driver know it is multithreaded.

My odbcinst.ini is setup as follows:
[PostgreSQL]
Description = ODBC for PostgreSQL
Driver = /usr/local/odbc/lib/libodbcpsql.so.2
Setup = /usr/local/odbc/lib/libodbcpsqlS.so.2
FileUsage = 1
CPTimeout = 1000
CPReuse = 20
Threading = 2

[ODBC]
Trace = no
TraceFile =
ForceTrace = No
Pooling = Yes

Any ideas???
