Did you compile from source or are you using the binaries we compiled?
The "CBlock::ReadFromDisk() : OpenBlockFile failed" is very odd, that should never happen. You aren't running with a -datadir on a network drive or something are you?
Compiled from source.
The datadir is on the local disk (LVM volume on the same physical disk as the OS).
run it in gdb, and use the "bt" command when a segfault occurs. Make sure to enable thread tracing, if that is not default / built in.
Thanks, I will do that. One doubt though. How can I enable thread tracing, or check whether it is enabled by default? Google tells me to use ptrace instead of gdb for thread tracing, but I suspect this is not what you want me to do.
