  68320   Sun May 22 04:05:12 2016 Question Stan Turnerinparadisez3@yahoo.comQuestionWindows3elog service crashes frequently

We have always had issues with eLOG crashing intermittently...  I upgraded from Server 2003 to Server 2008 about a year ago to try to reduce the issues...  which really didn't help.

The service now seems to crash every week...  (getting worse)...  Is anyone seeing these issues in Windows servers?  Any suggestions??

Joe,

Run the command 
`limit' (if you are running tcsh) and `ulimit -a' if you are running bash
(these are command line programs that will tell you the resources you are
allowed to use.  Look at filesize, datasize, and stacksize - these need to be
8M or so)

You can increase these by typing, e.g.,

limit filesize unlimited
limit datasize unlimited
limit stacksize unlimited

(the equivalent command for bash are `ulimit -f unlimited', `ulimit -d
unlimited' and `ulimit -s unlimited', without the quotes)

which will increase the limits to the max imposed by the administrator.  
If that doesn't increase your limits, you will have to contact the admin to
have them raised system wide.

If you are the administrator/sole user, you can set them to the max in the file:

/etc/rc.common.

I have included the following at the end of the file:

##
# Enable coredumps if requested.
##
if [ "${COREDUMPS:=-NO-}" = "-YES-" ]; then
    ulimit -c unlimited
    ulimit -d unlimited
    ulimit -s unlimited
fi


and I have put this in /etc/hostconfig

COREDUMPS=-YES-

Hope this helps - if that doesn't fix it, sorry!

  1806   Wed Apr 12 19:22:34 2006 Question Sridhar Anandakrishnansak@essc.psu.eduQuestionAll Can a field value be calculated during display?
I have a logbook which is a Calendar/Appointment book with Attributes: "Appointment DateTime", Place, etc.

I would like another Attribute called "When" whose value is calculated from Today's Date - Appointment date (so for example I could display today's appointments in red...). This calculation has to take place each time the logbook is displayed...

Possible? Useful?

Thanks,
Sridhar.

ELOG seems to enter a loop when you do certain opeations on certain messages: I moved a message to a different logbook and the deamon just gets stuck.

If I restart the daemon, the message was in fact moved: I can move it back to its original destination without problems.

I started in GDB and break with ctrl-C when the process gets stuck, to be told :

Program received signal SIGINT, Interrupt.
0x000000000040a968 in find_thread_head ()

I then made a core dump.

I put the files here: http://cern.ch/poulsen2/elog-error-report-110430.zip (they are too big to upload).

I get into the same problem in other circumstances such as when opening some threads (maybe because they contain "Reply-to" references to non-existing messages, but I have problems reproducing this on the test installation.

I should maybe also submit the incriminating thread.

 1. It appears that some times find_thread_head is called with message references that do not exist. That is not good.

I put in a little check like this  before seeing if the message has an "in_reply_to" reference:

The line:

if (lbs->el_index[i].in_reply_to)

becomes:

if (i < *lbs->n_el_index && lbs->el_index[i].in_reply_to)
 

2. The trouble started when I deleted a message in the middle of a thread, which left the thread badly "connected" (references to a deleted message).

3. Also, when a thread is badly connected, it is a problem moving messages to a different logbook. ELOG complains that it cannot access the message (with the invalid reference). But ELOG should ignore it, since the message was deleted.

 It would be nice to have this corrected. The problem occurs when you select (read) a message which refers to another message via "In-reply-to", and this message does not exist.

Hi,

First of all, thanks for all the great work, we all thank you here at SESAME synchrotron smiley

I am trying to set a conditional attribute where selecting one option in that attribute should trigger multiple outcomes as shown below:

Options Type = Fault{1_1&1_2}, Test{2_1&2_2}, Report{2_1&2_2}

{1_1} Options Fault Status = Open{a}, Fixed{b}
{2_1} Preset Fault Status = NA
{1_2} Preset Icon = attn.png
{2_2} Preset Icon = icon1.gif

I tries adding "&" as shown but that didn't work, my goal is to have 1_1 and 1_2 triggered whenever I select "Fault" as type, how can I do that?

Thanks in advance.

Cheers,

Sofian.

Thanks Andreas,

Works great.

I tried reading the documentation on this but I was not able to deduce this solution.

Thanks a lot again.

Hi Sofian,

it should work like this:

Options Type = Fault{1}, Test{2}, Report{3}

{1} Options Fault Status = Open{a}, Fixed{b}
{2,3} Preset Fault Status = NA
{1} Preset Icon = attn.png
{2,3} Preset Icon = icon1.gif

It is described under "Multiple conditions" in the documentation (https://midas.psi.ch/elog/config.html#conditional).

Cheers and good luck!
