Thread: stack smashing detected
Hi!
I'm trying test a version extended of Postgresql, but when I run a command after 9 times, I receive this message in psql:
***stack smashing detected***
And Log said that postgres terminated with signal 6.
I increased buffer to 120MB and the linux buffer (shmmax) to 2GB.
What value can I put to max_connections?
And can you help me with this error (stack smashing)? I tried run this with Ubuntu, Debian and Fedora, but I have not success.
Sorry about my english.
Thanks,
Ana Carolina

You're thinking in the wrong terms entirely. This is a bug that you
need to find/fix in whatever your extension is. I'd look for things
like overrunning a fixed-size array allocated as a local variable.

There must be more going on than you're saying.
