Strange behaviour

Hi folks !

Where to start looking for cure ?

I have a database, simple one, about teams and team members, nothing fancy
about it, straight forward, add, mod and del teams and their members. Four
tables team_type_1, members_type_1, team_type_2 and members_type_2.

Whatever I do with this db, I have another postmaster and httpd process
started and running and these keep piling up until everything freezes and at
the same time I see this error on an other terminal window for every access,
be it even a simple select:

bash-2.04$ postmaster -D /usr/share/pgdata/

I have default / install config on RH 7.1 and Pg is 7.1.3 which comes with RH
distribution. Nothing like this on any other db. I have scheduled vacuum for
all dbs every night. All runs on 800Mhz / 256 RAM machine. I (and others)
access the dbs via ColdFusion / web ( yes, some might have opinions about
this, but don't think it is the issue here )

What is the max or recommended max number of dbs for the system. I have now
just under 40 small ones, 'biggest' contains 11000 rows. The dump file of all
dbs is about 4.5 MB, which can't be nothing yet ?

I am a bit lost here, so please give a hint.

TIA,
