Out of Memory Errors

All,

I am having a problem with out of memory errors and I am wondering if it is
something going on with the postgres.

I review my error log and find the following.

Out of memory!
[Tue Apr 11 14:54:08 2000] [error] [client 209.208.191.31] Premature end of
script headers: /home/cycle/cgi-bin/bidreq.cgi
DBD::Pg::st execute failed: pqReadData() -- backend closed the channel
unexpectedly.
This probably means the backend terminated abnormally before or while
processing the request.

There are also a few errors like this

1) disconnect(DBI::db=HASH(0x825f738)) invalidates 1 active statement.
Either destroy statement handles or call finish on them before
disconnecting. at /home/cycle/cgi-bin/dealer.cgi line 102, <confHandle>
chunk 128.

2) DBD::Pg::db selectrow_array failed: ERROR: parser: parse error at or
near "null"

I understand the cause of error 1 & 2,
- somewhere one of my scripts does not terminate the statement handle before
exiting
- I must be doing a search on a null variable causing error 2.

Is it possible that these two errors are causing my problem? If I exit a
script with out properly terminating the db handle or statement handle does
that take up resources on postgres, or is it not something to worry about.

Thank you in advance
