[rt-users] RT Couldn't write to session directory '/usr/local/var/session_data'

[Fahd Sultan]

RT: rt-3-0-4
RedHat: 9, kernel: 2.4.20-6

I'm getting this error:

RT Couldn't write to session directory '/usr/local/var/session_data': DBD::mysql::st execute failed: Duplicate entry '255fe0d2e7f33beb41aa65a86e2d7d99' for key 1 at /usr/lib/perl5/site_perl/5.8.0/Apache/Session/Store/DBI.pm line 42.

. Check that this dir ectory's permissions are correct. at /usr/local/share/html/Elements/SetupSessionCookie line 60.

There is more trace information which is at the end on this email.

I've checked the permission on the directory: its owned by 
nobody/nobody,  apache runs as user nobody.

drwxrwx---    2 nobody   nobody       4096 Jul 17 15:57 .
drwxr-xr-x    5 root     root         4096 Jul 17 15:57 ..

I'm really not sure whats going on here any help would be appriciated.

thanks
