Bug description: File upload error
Description:
------------
I am using iPlanet 6.0 SP5, Zend 2.5.7 and PHP 5.0.3 on a 64 bit Solaris 9
SunFire V880 (4x4GHz CPU, 8Gb RAM). I have a problem with an HTTP POST
command that attempts to upload a file onto the web server and a
consistent "File upload error - unable to create a temporary file in
Unknown on line 0" error message appears in the error logs. The
upload_tmp_dir directory is set to /tmp. The error message disappears with
a web server daemon reset (stop/start the web server daemon), but the error
begins to occur within 2 to 24 hours again. When the errors occur, the /tmp
directory begins to accumulate with php[web_server_pid] files that are zero
bytes in size. My upload_max_filesize parameter is configured to 2Mb,
however the uploaded files are never above 50kb. I've tried many suggested
fixes from the php.net bug reports area, but to no avail. Thanks in advance
for your help!
