[stunnel-users] INTERNAL ERROR: s_poll_wait returned 1, but no descriptor is ready

[Florian Gossin]

HI,

I'm trying to setup a connection from JDBC to pgbouncer through stunnel.
Unfortunately, I get the above error message when I try to connect.

Here are the logs from stunnel:

In pgbouncer, I get the following error:
Pooler Error: bad packet header: '70'

And in JDBC, the following exception:
GRAVE: ERROR: bad packet header: '70'
org.postgresql.util.PSQLException: ERROR: bad packet header: '70'

Where might be the problem ? Does the stunnel parameter protocol=pgsql work
with JDBC ?

Thank you
