Forum OpenACS Q&A: Multiple openacs in a box problem!

Hi all! I am getting problems with two openacs installations in the same box with the same database server. I have RedHat6.2 and PG7.0.2, for the first server everything is going well, but then I did another database, openacs and start the aolserver in other port (the .tcl file is ok). I can't connect (the most of the times), the problems seems to be that a handle can't be allocated, I don't know why? here's part of my log file with the second openacs:
