The error message means that the process received SIGALRM, which is like an alarm clock ringing, saying 'wake up'.
Apparently the asccron.ksh script does not handle signals.
Since you get the same error when you are in vi, it looks like there is another process that is running as a daemon or maybe a detached process that looks for 'asscron' or some very similar file name, then sends a SIGALRM to the process that has the file.
Does the asscron.ksh script create another process?
Edit:
will stop the process from crashing, if it's added near the top of the script. But you still need to find out what is sending signal.

Hello
I have a server HP ES40 with unix 5.1B, and if i open from Start-Programs-IN Tools-GUI/pfmalarm/Alarm-start monitoring , I receive this error message "IOR : STRING IS TOO LONG ! MAXIMUM SIZE = 1024"
Anybody heard about this error?
Thanks

I am trying to write a signal to exit when a process times out. What I have come up with from poking around the web is this.
#!/usr/bin/perl
eval {
local $SIG{ALRM} = sub { die "alarm clock restart" };
alarm 10;

I am trying to write a program that will;

I can't make it work. Any hints... (17 Replies)

I'm writing a function right now, and I want to set an alarm to avoid a timeout, here's the general idea of my code:

amt = read(fd, &t->buf, TASKBUFSIZ - tailpos); //do a read
when the alarm goes off, i want to check the value of "amt"

trap
trap(1) User Commands trap(1)NAME
trap, onintr - shell built-in functions to respond to (hardware) signals
SYNOPSIS
sh
trap [ argument n [n2...]]
csh
onintr [-| label]
ksh
*trap [ arg sig [ sig2...]]
DESCRIPTION
sh
The trap command argument is to be read and executed when the shell receives numeric or symbolic signal(s) (n). (Note: argument is scanned
once when the trap is set and once when the trap is taken.) Trap commands are executed in order of signal number or corresponding symbolic
names. Any attempt to set a trap on a signal that was ignored on entry to the current shell is ineffective. An attempt to trap on signal 11
(memory fault) produces an error. If argument is absent all trap(s) n are reset to their original values. If argument is the null string
this signal is ignored by the shell and by the commands it invokes. If n is 0 the command argument is executed on exit from the shell. The
trap command with no arguments prints a list of commands associated with each signal number.
csh
onintr controls the action of the shell on interrupts. With no arguments, onintr restores the default action of the shell on interrupts.
(The shell terminates shell scripts and returns to the terminal command input level). With the - argument, the shell ignores all inter-
rupts. With a label argument, the shell executes a goto label when an interrupt is received or a child process terminates because it was
interrupted.
ksh
trap uses arg as a command to be read and executed when the shell receives signal(s) sig. (Note that arg is scanned once when the trap is
set and once when the trap is taken.) Each sig can be given as a number or as the name of the signal. trap commands are executed in order
of signal number. Any attempt to set a trap on a signal that was ignored on entry to the current shell is ineffective. If arg is omitted
or is -, then the trap(s) for each sig are reset to their original values. If arg is the null (the empty string, e.g., "" ) string then
this signal is ignored by the shell and by the commands it invokes. If sig is ERR then arg will be executed whenever a command has a non-
zero exit status. If sig is DEBUG then arg will be executed after each command. If sig is 0 or EXIT for a trap set outside any function
then the command arg is executed on exit from the shell. The trap command with no arguments prints a list of commands associated with each
signal number.
On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
