exec function

[Anon]

I am trying to call a external executable using the exec command. The problem is for 3 months this command worked perfectly. Then it just stopped.
I have re-installed php, checked log files for any information, and went into my backups to replace the files.
Here is the line:

$call2 = exec("./gwClient $filepass2 2>&1", $ret);

$filepass2: holds the location and the name of the file that is passed the external exe--gwClient

Any suggestions??

1) does it return an error? try passthru or system and see what the command returns.

2) can you run the same command line as the user that apache is logged on as? This may be a permissions issue.

No, it does not return any errors, and I will take a look at the apache.
But the thing is I have the same call on about 8 other pages (these pages are calling the same external exe, but different from the one I am having trouble with) and it is working on all eight pages.

I have tried both passthru and system.
'passthru' returns nothing.
'system' returns nothing, but the return status code for is 127.
And yes....I can run the same command line as the user that apache is logged on as.
