An assertion in the Lustre client is triggered by the following calls, which leads to a kernel crash during executing the write syscall shown below:
// Strace
open("./file1", O_RDWR|O_CREAT|O_EXCL|O_TRUNC|O_DIRECT|O_LARGEFILE|O_NOFOLLOW, 000) = 3
write(3, "#! ./file1\n}!F\270\v\21k;{\310T+z\311-\311@:\312\27S"..., 3595
