does following code cause system crash

[subtelo]

For more than one time, once I run the following code to untar several files (total ~4G), the remote server always crash. I use ssh to reach remote server. The final data is around ~30G. I am wondering does this code cause memory leak? Or it eat all CPU space? I do not have any knowledge regarding the hardware.
ANY input is appreciated.

############
#!/usr/bin/perl

use strict;

foreach my $i (0..59)
{
my $com = "tar -xvzf data$i.tgz";
`$com`;
}

Multiple 'my' declaration may cause problems.
try -

############
#!/usr/bin/perl

use strict;
[red]my $com;[/red]
foreach my $i (0..59)
{
    $com = "tar -xvzf data$i.tgz";
    `$com`;
}

Hmm, you are right. Multiple valuables may take more memory.

Any other comment?

Do all the files exist?
What happens if you only tar a single file?

Everything is fine when I only tar a single file. And all files are exist.
Every time after i ask the server admin to rebuilt the server, the script will go through and untar all files without any problem.
Next time I use the same code to untar same other different data, same problem will happen again.

Woo, there is a typo. What I mean is that I ask the server admin to reboot the server. Sorry for the misleading.

Use the full path to tar

The first code is correct. Using my in the loop localizes $com to inside the loop.

I posted before without actually reading your whole problem. I would check out the size of the .tgz files. Maybe there are more files or bigger files than you expect. I would add a check to see if the file exists ( -e ) before trying to untar it.
