Application calls the script but errors out

Hello Scrutinizer, Thanks. We have 3 SAP Application servers. The script is on only 1 of them. In my environment, the script is kicked up every time. However, it errors out and terminates 50% of the time so this should rule out the possibility that SAP called the script on other App servers. I appreciate your help. J Phang

Particularly vulnerable if you job is running at the same time as something large like a backup.

2) Maybe backup software is locking the file. (long shot)

3) I prefer pludi's idea. Automounter involved?

Also check the script file itself for funny characters.
Code:
sed -n l scriptfilename

Hi methyl, Thank you. I did a check on the points you had brought up.
1) That's a possibility. I'll need to investigate the number of open files in the day. It sounds logical because the script worked early in the morning before lots of people started arriving for work, it worked occasionally during the day and then almost 100% after 5 pm in the afternoon when most people got off.
2) Our backup software runs against a cloned copy of the disks via symclone. Plus the error which says that the ssh binary isn't found instead of other errors. Less likely this could be it.
3) I've checked again and can confirm that /bin is directly under root and not mounted. Autofs is inactive. Also, if I run this script over a SSH session, it'll work 100%.
4) I've ran an equivalent command over previously "cat -vet" to check for quite the same thing. The command ran when I kicked it off interactively so it shouldn't be a character issue.
Thanks for the suggestions. At least I know what else to check for tomorrow. Being in Asia means it's 3.10am now. My apologies if I couldn't reply more quickly.

LEARN ABOUT SUSE

xsession.options

Xsession.options(5)						File Formats Manual					       Xsession.options(5)

NAME

       Xsession.options - configuration options for Xsession(5)

DESCRIPTION

       /etc/X11/Xsession.options  contains a set of flags that determine some of the behavior of the Xsession(5) Bourne shell (sh(1)) script.  See
       the Xsession(5) manpage for further information.

       Xsession.options may contain comments, which begin with a hash mark ('#') and end at the next newline, just like comments in shell scripts.
       The  rest  of  the  file consists of options which are expressed as words separated by hyphens, with only one option per line.  Options are
       enabled by simply placing them in the file; they are disabled by prefixing the option name with 'no-'.

       Available options are:

       allow-failsafe
	      If the 'failsafe' argument is passed to the Xsession script, an emergency X session is  invoked,	consisting  of	only  an  x-termi-
	      nal-emulator(1)  in  the	upper-left hand corner of the screen.  No window manager is started.  If an x-terminal-emulator program is
	      not available, the session exits immediately.

       allow-user-resources
	      If users have a file called .Xresources in their home directories, these resources will be merged with the default X resources  when
	      they log in.

       allow-user-xsession
	      If users have an executable file called .xsession in their home directories, it can be used as the startup program for the X session
	      (see Xsession(5)).  If the file is present but not executable, it may still be used, but is assumed to be a Bourne shell script, and
	      executed with sh(1).

       use-session-dbus
	      If the dbus package is installed, the session bus will be activated at X session launch.

       use-ssh-agent
	      If  the  ssh-agent(1)  program  is  available  and  no agent process appears to be running already, the X session will be invoked by
	      exec'ing ssh-agent with the startup command, instead of the startup command directly.

       All of the above options are enabled by default.  Additional options may be supported by the local  administrator.   Xsession(5)  describes
       how this is accomplished.

AUTHORS

       Stephen Early, Mark Eichin, and Branden Robinson developed Debian's X session handling scripts.	Branden Robinson wrote this manual page.
