Bug description:  SNMP timeouts on specific OIDs and truncating of certain OID return strings

Description:
------------
When running making specific SNMP get/walks against Windows 2003 or
Windows XP the following has been seen to occur

1.  Sometimes the SNMP walk against .1.3.6.1.2.1.25.2.3 the request times
out.  If I use GetIf to walk the OID the results are displayed, but PHP
fails randomly

2.  When viewing .1.3.6.1.2.1.25.4.2.1.4 with GetIf the file paths/names
are displayed in full, but when I do a SNMP walk the output is truncated.




Reproduce code:
---------------
The code can be downloaded from  http://sourceforge.net/users/lsms-mrtg/

The example windows code is in the package.

Example of the truncated output

<?php
print_R(snmpwalk("127.0.0.1","public", ".1.3.6.1.2.1.25.4.2.1.4"));

?>

Expected result:
----------------
The full program paths displayed, where appropriate.


Actual result:
--------------
