temp_buffers is probably to high, work_mem is definitively high...
what you're saying with work_mem=128MB and max_connections=50 is
that at some point it could be 128x50 MB of memory used (that is more
memory than you have)
probably checkpoint_timeout, random_page_cost and effective_cache_size needs
a revision too
PS: about log the slow sentences... put log_statements in 'none' and
log_min_duration_statement in something meaningful i always start with 3s
and try to clean most i can before lower that value
