Aug 15

(RD) 21:30 Error - Oracle could not extend glasttrend table space. Ian fixed it, but is wondering why the oracle alarm system did not catch this before it ran out.

Aug 13

(WBF) Restarted tomcat09. I think memory was ~70%. Pipeline frontend, shift schedule, and run quality were all giving java stack traces.

Aug 12

(RD) Two sets of problems. The 2 Black Boxes were serviced to replace faulty sensors. Sadly, a group of cores in them was not turned off in LSF before turning them off, so a mess was made in L1. Then it seems a different set of cores developed AFS access problems. They were shut down to LSF. John Bartelt will look into how the group of bali's escape glastdataq shutdown.

Aug 8

(MT) 06:30 Restarted Prod Crawler. It was stuck with the usual xrootd waiting messages.
(TJ) I think the problem may have been caused by running out of memory due to large skimmed FITS files I registered in the datacat last night. I have a more efficient way of reading FITS file from xrootd which I should install into the crawler.

Aug 2

(RD) 07:15 Michael reported overnight that some mount points under $GLAST_EXT in afs seem offline. I've sent mail to unix-admin about it, and detailed a bit in opsproblist. If they don't get to it this morning, they should be paged. Renata rebooted the server around 08:45.

July 29

(MT) 12:15 Restarted tomcat12. It ran out of memory.

July 26

(TJ) /scratch on glastlnx16 had filled up. Nagios was complaining about glast-tomcat09 although it was mostly still functional. The cause was a test version of confluence which had filled the scratch disk with backup files. The files have been deleted and backup has been disabled on this instance of confluence.

July 22

(RD) 00:23 Got phone call from Elliott that DQM was unresponsive. Confirmed and restarted tomcat07. Seems ok now.

July 20

(TJ) A new application has been installed on glast-tomcat09 to make the CountdownClock available at: http://glast-ground.slac.stanford.edu/CountdownClock/

All

Is
it
the
same
script
that
ran
successfully
yesterday.
The
database
was
waiting
on
sql*net
message
from
client
which
usually
means
a
process
has
gone
idle.
The

both
went
idle
after
issue
insert
into
DQMTRENDDATAID
(dataid,
loweredge,
upperedge,

values(:1,:2,:3,:4)
There
was
no
further
action
being
taken
by
either
session
such
as
reads,
execute
counts,
etc.
So
either
the
process
was
idle
or
it
didn't
have
enough
resource
to
even
attempt
what
was
to
be
executed
next.
I
think
for
now
the
old
script
is
probably
best
to
run.
It
would
be
nice
is
serialization
wasn't
done
via

It
would
also
be
good

I

TelemetryTrending application crashes

The telemetry trending application had to be restarted a couple of times in the last 24 hours. This has been caused by large memory usage when tabulating the data IOT-87@jira.

I am working on a fix.

In the meantime monitor the memory usage of tomcat12 from the Server Monitoring application.
When memory gets close to 90% try clicking on "Force GC" (If you don't see this link you need to be added to the ServerMonitoringAdmin group). If garbage collection does not reduce the memory usage a crash might be imminent.

Two outstanding (new) issues: PFE-172@jira IFO-24@jira
