Using the PostgreSQL sources git clone git://git.postgresql.org/git/postgresql.git ./configure --enable-tap-tests --without-zlib --without-readline I can reproduce the problem reliably under "iotop -s0.1" when running make check-world -j16 -Otarget > PS: there is another iotop project written in C that might be more > robust and is definitely more featureful than the Python codebase so > please install the iotop-c Debian package and try it out. Ooh, I didn't know that. Yeah, this one doesn't seem to crash ... (It did crash on segfault once on SIGWINCH, namely when I changed gnome-terminal's font size to fit more lines in the output, but this is not very reproducible and I don't have a backtrace.) -- Álvaro Herrera 39°49'30"S 73°17'W — https://www.EnterpriseDB.com/ Al principio era UNIX, y UNIX habló y dijo: "Hello world\n". No dijo "Hello New Jersey\n", ni "Hello USA\n".
