How to debug using strace:

strace -s 80 -f -p 24274 2>&1 | stdbuf -i0 -o0 -e0 grep write

• -s number - Strace usually prints only a few chars for each system call, to make it print more chars use -s number of chars
• -f - Follow all threads opened by parent pid
• -p pid - Pid to follow
• 2>&1 - Reddirect stderr to stdin to be able to grep it
• stdbuf -i0 -o0 -e0 - Flush each line to grep
