Short Description
postgres dumps core in initlocalbuffer
Long Description
Hi,
first of all: postgres normally works very well. But in one case,
postgres dumps core, which prevents our project from being finshed.
Information: postgres 7.0.3, redhat 6.2, postgres compiled under redhat 7.1, linked statically (this works well!).
Machine has 256 Mb Memory, uses nearly no swap.
As said, most things work fine, but one part is a connection from a ODBC-Client Application. This also normally works
fine,but for one configuration it does not. The client uses Windows 2000, ODBC-Driver 6.5.0 (I think).
Postgres dumps core after some time, if the odbc application opens a new connection. To clarify this: there are
transactionsgoing through, but at some point in time (random), the newly started postgres crashes at once.
postgres-config:
/home/postgres7/bin/postmaster -o -o /var/log/postgres7.err.log -p 5433 -i -N 256 -S -o -F -o -S1024 -B1024 -o -B1024
-D/home/postgres7
There are at most 100 servers running...
Many thanks for you help, if there are questions, please ask!
Greetings
Florian
P.S. the machine is NOT out of memory! :-) And it already happened, when the executable has been compiled on the same
machine!
