I checked permissions on /tmp and it's open to all rw. Suggestions on where to look?

MKSTEMP(3)                 Linux Programmer's Manual                MKSTEMP(3)

NAME
       mkstemp - create a unique temporary file

SYNOPSIS
       #include <stdlib.h>

       int mkstemp(char *template);

DESCRIPTION
       The  mkstemp() function generates a unique temporary filename from template.  The last six characters of template must be
       XXXXXX and these are replaced with a string that makes the filename unique. The file is then created with mode read/write
       and  permissions  0666 (glibc 2.0.6 and earlier), 0600 (glibc 2.0.7 and later).  Since it will be modified, template must
       not be a string constant, but should be declared as a character array.  The file is opened with the open(2) O_EXCL  flag,
       guaranteeing that when mkstemp() returns successfully we are the only user.

should be from Zend Pdf library, since it looks mkstemp() is not a php function, but a C function.

it depends on the value of variable "template". assume it's "a.XXXXXX". then temporary file will be created at current working directory, not /tmp/. for more information, please check what user lsphp is running as, and the location of the php scripts and the directory permission.

Thanks for the reply. What about the following error?

2011-09-04 06:28:22.654 [ERROR] [208.69.120.120:61555-0#APVH_207.32.184.195_example.com] Failed to initialize VMemBuf.

Also, switching to apache the Pdf outputs as it should. It has to be an lsws/lsapi configuration issue somewhere. Just can't seem to figure out where.

FYI: lsws is running as apache:apache.

how about lsphp5?

I figured it out. /tmp/lshttpd/swap was not owned by the apache user for some reason. chown'ing to apache fixed the problem.

Thanks for your help.
