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!

  381   Mon Jun 30 02:41:33 2003 Entry Recai Oktasroktas@omu.edu.trBug fixMac OSX2.3.8Re: runtime error under Mac OS X 10.2
Seems a stack problem.  I don't have an OS X box to validate my guess.  I've
made a Google search with the keywords: EXC_BAD_ACCESS stack "os x"

Perhaps the following reply [1] might help...

  How big are they? You're probably running into the default stack size 
  limit, which is 512 KB. Try `unlimit stacksize` in your shell before 
  running, which will give you 65536 KB per stack.

Sridhar & Recai,

Thanks to both of you for the rapid and effective advice.  Fixing the limit corrected my problem.  
I think I last got tripped up this way 10 years ago...

I suppose that the advice to increase Mac OS X's default stacksize limit might make a fine entry 
in the FAQ or README file.

Thanks again,
Joe

I added a note in the installation instructions.

The reason why im asking if it can be done using the Execute option is because I need to have the message id of the entry that was submitted and in an external script i dont have access to the variable

Hi

Im just curious is it possible to run more then one command using Execute new = <command> or will i have to run a script to run muliple commands.

I tried using '&&' to seperate more then one command but it seems that the first one only gets executed and the rest are just ignored.

Regards

Kenzo

The command is passed to your shell, and some shells except more than one command. Most Linux shells accept commands separated by ';', which you can try yourself by entering for example: ls *.c; ls*.h

If i put the ';' into Execute the rest of the command becomes a comment thats why i was trying to use '&&' instead. If I encapulate the whole command in "" or '' then both commands are executed but the files im trying to write to gets created but no data is piped into it. When I use Execute with one command and pipe its output to a file everything works fine though.

As far as I know ELOG is recognising a configuration line as a comment only when it starts with a ';'.
I can assure you that ELOG does not treat the rest of the line as a comment when you use a ';' within a $shell() command: I do it a lot and it works fine. Here's a simple, generic example using the bash:

Preset Author = $shell(if [ $short_name = "Anonym" ] ;then echo $Author;else echo \"$long_name, $Author\";fi)
It adds $long_name to the Author field for non-anonymous entries.

Cheers Andreas
