"too big" and "not enough memory" errors in shell script
Hi,
This is odd, however here goes. There are several shell scripts that run in our production environment AIX 595 LPAR m/c, which has sufficient memory 14GB (physical memory) and horsepower 5CPUs. However from time to time we get the following errors in these shell scripts. The time when these happen there is not much activity going on and the errors seem to eventually go away since the scripts which are getting these types of errors are scheduled to run from TWS (maestro) and run all day long. They run just fine during the peak hours of acitivity on the box. Can someone tell me what to check or do for these types of errors.

rbash
RBASH(1) General Commands Manual RBASH(1)NAME
rbash - restricted bash, see bash(1)RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
