[Info-vax] Interpreting or reading DCPS dumps ?

Sun Aug 1 17:41:23 EDT 2010

Today I found something else that seems related to
DCPS that I didn't identify when this thread was active
some weeks (months?) ago.

It's some files in SYS$SYSTEM called PTHREAD_DUMP.LOG
We have 13 of these spread over time :

PTHREAD_DUMP.LOG;13     3/18    29-JUN-2010 09:25:00.16
PTHREAD_DUMP.LOG;12     3/18    15-JUN-2010 10:59:23.40
PTHREAD_DUMP.LOG;11     3/18    15-JUN-2010 10:58:36.63
PTHREAD_DUMP.LOG;10     3/18     9-JUN-2010 08:58:49.64
PTHREAD_DUMP.LOG;9      3/18     1-JUN-2010 10:13:15.10
PTHREAD_DUMP.LOG;8      3/18    31-MAY-2010 09:09:27.51
PTHREAD_DUMP.LOG;7      3/18    28-MAY-2010 12:43:03.19
PTHREAD_DUMP.LOG;6      3/18    27-MAY-2010 09:43:12.19
PTHREAD_DUMP.LOG;5      3/18    28-APR-2010 08:16:28.68
PTHREAD_DUMP.LOG;4      3/18    31-MAR-2010 06:39:21.18
PTHREAD_DUMP.LOG;3      3/18    24-MAR-2010 07:07:00.82
PTHREAD_DUMP.LOG;2      3/18    24-MAR-2010 06:16:33.85
PTHREAD_DUMP.LOG;1      3/18    15-SEP-2009 06:37:35.47

Below is what one of them looks like (the latest one). I
have no idea how to interpret this and I have not yet
tried to correlate this with our "spinning DCPS process"
problem.

Does the log below give anyone some "Aha!" feeling ? :-)
