Hello,
I have a large data set stored using version 6.4.2 on a Sun Ultra 30
(Solaris 2.6 - 384MB RAM). While trying to preform a somewhat
complex select on one of the larger tables from the psql> command
promplt, I am given the following error message then dumped out out psql:
pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.
We have lost the connection to the backend, so further processing is
impossible. Terminating.
If I try the same query from a cgi script written in perl, the script
comes back empty and this warningappears on my console screen:
WARNING: Sorry, no swap space to grow stack for pid 15195 (postgres)
The swap space on the system I'm using looks to be around 275MB and
it remains at about 1% capacity during the operation that bombed.
I've looked around the mail archives and have not found any similar
problems or solutions. Does anyone have any ideas? Thanks!
-Mark.
