Try the other command... Do not use xargs..

I am not sure what could be causing the error.

Code:
find /comptel4/elink/backup1/output/vas/NG0/ -name "*.GPX.Z" -exec zgrep -il $i {} \;

Same problem Smilie

Code:
/comptel4/elink/backup1/output/vas/NG0> ./ms.sh
./ms.sh: xrealloc: subst.c:5173: cannot allocate 268435456 bytes (536936448 bytes allocated)
/comptel4/elink/backup1/output/vas/NG0> more ms.sh
#!/usr/local/bin/bash

for i in `cat msisdn_u.txt`
do

find /comptel4/elink/backup1/output/vas/NG0/ -name "*GPX.Z" -exec zgrep -il $i {} \;

done

I found something on this

Can you give it a try and see?

This is a production box and I can't change any values unfortunately.

The files matching the pattern *GPX.Z are compressed text files or directories?
You could try:

Code:
find /comptel4/elink/backup1/output/vas/NG0/2013030[1-7]/ -type f -name '*GPX.Z' | xargs zgrep -f msisdn_u.txt

or:
Code:
find /comptel4/elink/backup1/output/vas/NG0/2013030[1-7]/ -type f -name '*GPX.Z' -exec zgrep -f msisdn_u.txt {} +

if your find implementation supports the {} + construct.
What's your operating system?

And, by the way, you could try your script with a different shell (different than bash).

done

You will continue to trigger that error so long as the contents of the txt file in the highlighted command substitution exceed your system's available memory (or process mem limit).
