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
