Bug Type: Program Execution
Operating System: Solaris 2.8
PHP Version: 4.3.3
New Comment:
Sorry, the 'expected result' is naturally just the output
of a ping process, ie:
PING blah: 56 data bytes
64 bytes from 192.168.5.1: icmp_seq=0. time=1. ms
64 bytes from 192.168.5.1: icmp_seq=1. time=0. ms
----blah PING Statistics----
2 packets transmitted, 2 packets received, 0% packet loss
round-trip (ms) min/avg/max = 0/0/1
And the actual result is the error I pasted under
expected output. Excuse my braindead first post.

Description:
------------
At certain times (no discernible load, nor any unusually
high memory or swap usage, etc.) all shell exec commands
fail. Typically it will last a short period of time, and
then all commands work fine. Restarting apache does not
appear to cure or improve the situation. Below are my
particulars.
My configure line:
./configure --with-apxs=/usr/local/apache/bin/apxs
--with-oracle=/opt/oracle --with-snmp=/usr/local --with-curl=/opt
--with-gd --with-zlib-dir=/usr/local/lib
Other information:
Sun E250, 2x296mhz, 1024MB RAM, gcc 2.95.2
Changes to php.ini from php.ini-dist:
register_globals = On
Here are some error examples from various execs:
Warning: shell_exec(): Unable to execute 'nslookup -timeout=3
10.130.0.1 2>/dev/null' in /usr/local/apache/htdocs/my.php on line 39
Warning: system(): Unable to fork [/opt/qip/usr/bin/qping -v -r 3 -t
250 10.130.2.163] in /usr/local/apache/htdocs/my.php on line 79
Warning: passthru(): Unable to fork [/opt/qip/usr/bin/qping -v -r 3 -t
250 10.130.2.163] in /usr/local/apache/htdocs/my.php on line 78
Reproduce code:
---------------
echo "<pre>"; system("ping -s $ip 56 10"); echo "</pre>";
Expected result:
----------------
Warning: system(): Unable to fork [ping -s 10.130.2.163 56 10] in
/usr/local/apache/htdocs/ping.php on line 55
Actual result:
--------------
Command simply doesn't execute, program continues without
a problem or error.
