I am having trouble with the pfiles command. The other pxxxx commands appear to
work fine but this one hangs. Here's the sequence of operations used to
generate the situation.
> grep scum (to cause the program to just sit and wait for input)
> ps shows:
100416 pts/1 0:00 grep
> pflags 100416 shows:
100416: grep scum
data model = _ILP32 flags = MSACCT|MSFORK
/1: flags = ASLEEP read(0x0,0x4041f0,0x2000)
> pfiles 100416 hangs
> pflags 100416 now shows:
100416: grep scum
data model = _ILP32 flags = RLC|MSACCT|MSFORK
entryset = 0x00000000 0x00000000 0x00000000 0x00000000
0x00000000 0x00000000 0x10000000 0x00000000
/1: flags = STOPPED|ISTOP|ASLEEP read(0x0,0x4041f0,0x2000)
why = PR_REQUESTED
/2: flags = DETACH|AGENT|ASLEEP read(0x0,0x4041f0,0x2000)
sigmask = 0xffbffeff,0x0000ffff
> pflags of pfiles shows:
100427: pfiles 100416
data model = _LP64 flags = MSACCT|MSFORK
/1: flags = ASLEEP write(0x84,0x7ffffffe918,0x10)
sigmask = 0xffbffeff,0x0000fff7
A trace shows that pfiles is waiting on the cv_waituntil_sig in pr_wait().
Evidently whatever should be signaling the cv being waited upon isn't. What is
the mechanism that should be taking place here?
