Hi all
 
Im using cygin install when the cygwin install version 2.457.2.2 on
Windows XP professional SP2, on an IBM ThinkPad Dual Processor T60.
 
I run a unix script from a bigger ant script, which used to work fine on
a single processor laptop. Now it works intermittently 
 
The Unix script is this:
 
#START
export SRC=$1
 
find $SRC -type d -name 'CVS' | xargs -i rm -rf {}
 
mv $SRC/tres/src/java/com/traderoot/core/
$SRC/tres/src/java/com/traderoot/cfgcore
#for jaxb generated source
mv $SRC/com/traderoot/core/ $SRC/com/traderoot/cfgcore
 
grep -Rl  'com.traderoot.core' $SRC | xargs -i ./replace.sh
's/com\.traderoot\.core/com.traderoot.cfgcore/g' {} 
grep -Rl  'com/traderoot/core' $SRC | xargs -i ./replace.sh
's#com/traderoot/core#com/traderoot/cfgcore#g' {}
grep -Rl  'com.traderoot.tools' $SRC | xargs -i ./replace.sh
's/com\.traderoot\.tools/com.traderoot.cfgtools/g' {}
 
#END
 
On the times when it does not work it spews out:
 
[exec] + xargs -i ./replace.sh
's/com\.traderoot\.tools/com.traderoot.cfgtools/g' '{}'
     [exec] replacing in
bootloadergensrc/com/traderoot/cfgtools/artifact/jaxb/Additionaldata.jav

error 487
     [exec] xargs: cannot fork: Resource temporarily unavailable
 
 
Could this be because of the dual processor where somehow the one
process is left hanging waiting for the other? Anyone experienced this
issue before...? can't find anything on the archives...

Jose Correia
