Gentlemen,

we're trying to run a script with Tivoli on several NT servers.
In this script we use at several positions the tr.exe to translate mixedcase strings to lowercase. 
We use it in several syntaxes: param=`echo $parameter | tr 'A-Z' 'a-z` and echo $parameter | tr 'A-Z' 'a-z'.
We noticed that on a regular basis tr and sh processes got stuck and do no complete. Looking at a trace,
generated with the set -vx command, shows several errors, like the ones stpecified below.

How are they caused and how can we avoid this ?

Kind regards,  Ronald van Gogh
