Still nothing to show 4 blocked processes (where it is sitting right now):
pluto# ps ax -O ppid,flags,mwchan | awk '($6 ~ /^D/ || $6 == "STAT") && $3 !~ /^20.$/'
PID PPID F MWCHAN TT STAT TIME COMMAND
pluto# ps ax -O ppid,flags,mwchan | awk '($6 ~ /^D/ || $6 == "STAT") && $3 !~ /^20.$/'
PID PPID F MWCHAN TT STAT TIME COMMAND
pluto# ps ax -O ppid,flags,mwchan | awk '($6 ~ /^D/ || $6 == "STAT") && $3 !~ /^20.$/'
PID PPID F MWCHAN TT STAT TIME COMMAND
