396.0. "New ENS actions fail to initiate, however existing actions still functional" by CSC32::C_TOWNSEND () Wed Sep 07 1994 23:07

Hello - 

I don't know where to go with this one, so the following will be text 
from questions I have already asked the customer about this ENS problem.

"The problem seems systemic in that once it starts happening, it happens
to all actions (regardless of nature) that ENS tries to start.  Existing
connections to ENS (processes that have been around for awhile) continue
to work fine and receive events.  ENS seems unable to start new
instances of any actions. 

Once the problem starts happening, the actions fail to start regardless
of which node triggers the events. It happens to all new instances of
all actions and all filters for all nodes and all events, once it starts
happening. 

A little investigation (and defining CONSOLE$DEBUG to be TRUE in the
startup procedure) tells me the following things: 

  1. Files to run the action are created in CONSOLE$TMP, but the
     files are empty (0/0 blocks).  The files are not deleted or
     purged, but continue to build up.

  2. The file CONSOLE$TMP:CONSOLE_NOTIFY_OUTPUT.LOG shows the following
     messages (for example):

     CONSOLE$ENS_DAEMON: Failed to create file 
     CONSOLE$TMP:Multi-Line__002.COM for action

     The messages repeat for every action that ENS fails to start. "
  
The customer has to shutdown and restart PCM in order to recover full 
functionality of ENS.  Any clues or additional troubleshooting tips?

Thanks in advance,
Connie

Connie,

  I havnt seen this before, is there enough disk space to create
  the files in the tmp directory?

  According to the code, this message is as a resulkt of the following...


if ((fp = fopen (running->actfile, "w")) == NULL)
    {
        fprintf(stderr,"%s: Failed to create file %s for action\n",
                        CM_ENS_DAEMON_IMAGE, running->actfile);

... etc...

  So, it would appear that that we cant open the file for some reason, I
  will add an extra bit to the error message to output the errno value, this
  will go into the final (not the one I sent you details on) patch kit, so,
  maybe your customer could install that next week and see what happens.

Cheers,
Phil

Phil -

The question has been asked about sufficient disk space, and the customer
assures me that free space is not an issue.  Send me mail when you have a
kit that we can use to debug the problem.  Since this is an intermittent
problem, the feedback timeframe is unpredictable.

Thanks again,
Connie
