Thx for quick reply and nudge in right direction. I have posted what I did in case that helps anybody else. I have a questions regarding the limits I increased (see details below). Are there any risks associated with having these increased limits, especially the one in my first post.
I figured out previously to your reply that the limit was around 10M. Sure enough this morning I went and checked the logs and found this error after trying to upload a too large file,
Jan 29 17:56:14 server1 httpd: PHP Warning: upload_max_filesize of 10485760 bytes exceeded - file [userfile[]=IM000988.MPG] not saved in Unknown on line 0
I made the following changes;
Jan 29 22:10:02 server1 /sbin/e-smith/db[23729]: /home/e-smith/db/configuration: OLD php=service|AllowUrlFopen|Off|status|enabled
Jan 29 22:10:02 server1 /sbin/e-smith/db[23729]: /home/e-smith/db/configuration: NEW php=service|AllowUrlFopen|Off|UploadMaxFilesize|30M|status|enabled
Jan 29 22:10:36 server1 httpd-e-smith: Restarting httpd-e-smith succeeded
Jan 29 22:10:46 server1 sshd(pam_unix)[23634]: session closed for user root
Now when trying to upload larger file I get this error;
Jan 29 22:11:34 server1 httpd: PHP Warning: POST Content-Length of 22384852 bytes exceeds the limit of 20971520 bytes in Unknown on line 0
I made the following changes;
Jan 30 05:12:41 server1 /sbin/e-smith/db[27440]: /home/e-smith/db/configuration: OLD php=service|AllowUrlFopen|Off|UploadMaxFilesize|30M|status|enabled
Jan 30 05:12:41 server1 /sbin/e-smith/db[27440]: /home/e-smith/db/configuration: NEW php=service|AllowUrlFopen|Off|PostMaxSize|30M|UploadMaxFilesize|30M|status|enabled
Jan 30 05:13:14 server1 httpd-e-smith: Restarting httpd-e-smith succeeded
This allowed me to upload files of up to 30M but not files adding up to more than 30M, i.e. I had 3 files of 20M each that I had to load in separate operations.
