Great- I'm glad I was able to help.

Phil! It was the offset type declared as an int instead of uint64_t.
Thanks for getting back to me so quickly. Super helpful.

Are you using the asynchronous interface (PVFS_isys_io() followed
by PVFS_sys_wait() or similar)? If so, it looks like an invalid
op id might have been passed into the latter. You might want to
check and make sure that PVFS_isys_io() didn't return an error code.
The above segfaults occur when the assertion fails.
I'm testing the write capabilities of orangefs-2.8.4 in the API I
built. I can successfully write 2GB, but when I try to write a
larger file, I consistently get the error above just after the
2GB mark. Know any causes of this error type during a write? Is
there a configuration I have overlooked?
I haven't run into this in a while, but 2 GB is the limit of an
offset that is stored in a 32 bit integer. You might want to
double check that you are using a large enough integer for the
offset, or that you are using an off_t and compiling with large
file support if you are on a 32 bit machine.

Thanks,
