Postgres process terminating

Hi all, I'm currently running postgres-7.4.12 with slony-1.0.5 and am seeing
the below postgres errors:

This causes slony to die on all clusters as well as our web applications.

In google'ing for "FATAL: 57P03: the database system is starting up" I
noticed other people having similar issues but I not been able to locate a
fix.

This morning I dropped all slony schema's from the database and am
continuing to re-create my clusters one by one and have not seeing these
errors thus far.

What I am interested in is a description of the above error log.

Any help is appreciated!

Thanks.
