[SOLVED] Warning: Unknown: open(/tmp/sess_xxxxxxxxxx, O_RDWR) failed: Permission ...

Hi all,

Recently I am getting this message from time to time when loading a php page.

Code:

Warning: Unknown: open(/tmp/sess_xxxxxxxxxxxx, O_RDWR) failed: Permission denied (13) in Unknown on line 0

I don't know at what stage of changing the php script this issue was introduced.
And to be honest, I would think it is not related to the php script.

Anyone got this error or can point me out what is going wrong?

I didn't do any OS update.

I have used google but could not come up with a solution.

Thanks in advance

Do you have space in your /tmp directory? Also, what permissions is your /tmp area mounted with?

I do have space:

Code:

df -h /tmp
Filesystem     Size    Used   Avail Capacity  Mounted on
/dev/ad0s1e    496M     22K    456M     0%    /tmp

Permissions:

Code:

ls -ldh /tmp/
drwxrwxrwt  9 root  wheel   1.0K Jul 31 03:04 /tmp/

Note that I am not always getting this message.
I am using jquery to refresh a div tag.
So each 10 seconds the contents get reloaded.
I get this message frequently.

I just noticed I am experiencing this issue with phpMyAdmin as well.

I have rebooted the server and the issue seems to have gone away. :s
