Failed to get language information for Project Server

[akae]

After some months of relax, MOPS started throwing new "random error messages" with apparently no action from users or admins. The topic of the new error is
Failed to get language information for Project Server ( Error 6058 ) and, after a little googleing, I figure out that it is caused by a bad access.
The error is reported on random days, but always at 2:20 AM, and repeats in ranges of 20' ( 2:40, 3:00, 4:00, 4:20 ... ) until 9:00 AM, when it stops.

The logs report some 401: Unauthorized:

I have checked the firewall logs and we have the usual attacks from China and Germany, nothing atypical, but no related with SS or port 12345 where MOPS SS is.

Any idea? Should I call Ghostbusters?
Thanks!

Update:
I'm suspecting MS Outlook 2007 calendar sync plugin...

Couple questions:

1. What language is Project Server/WSS (meaning did you install the Spanish version, or the English version with the Spanish language pack)?
2. What language is Outlook?

They are both configured to use Spanish as default language, because they are Spanish versions. I discarded that it was an actual language problem when I tested it with a laptop with sweden / japanese versions of Outlook and showed no problems.

PWA Versión: 12.0.0.6219
Outlook Versión: 12.0.0.6316.5000

Hm.

I would check the IIS logs to see if I can figure out the client and the call it is making. I would also increase the verbosity of the diagnostic logging and see if anything more useful shows up.

It seems that the access that provides the errors are made by the server itself. xxx.xxx.xxx.xxx is the IP of the server.

I had previous errors ( I posted them to this forums ) with "which services are runned by who" but I though they were solved...
According to the IIS Logs, the account Administrador is trying to login with a Mozilla browser, but I'm sure no one has the Administrator account password, and I'm also sure I was not browsing the PWA at the time the error was reported. There is an updated Firefox installed at the server, but it is not used to access PWA, and the version of Internet Explorer is 7 and causes no errors when login in.
Do we have a ghost in the shell? Any brilliant idea?
Thanks!

Update:
hmmmm... I think I'm getting closer:

 2008-08-13 09:00:04 W3SVC746553835 xxx.xxx.xxx.xxx GET /PWA/_layouts/AccessDenied.aspx Source=http%3A%2F%2Furl%2Eof%2Ethe%2EPWASERVER%3Aport%2Fpwa%2Ftasks%2Easpx 12345 PROJECT-SERVER\Sh.Serv.Search xxx.xxx.xxx.xxx Mozilla/4.0+(compatible;+MSIE+4.01;+Windows+NT;+MS+Search+5.0+Robot) 200 0 0

This is the user that runs the Shared Services Search service. I didn't manage to get it working properly and It caused several errors while running as a service account or Administrator Account... It is probable that the error is caused by a missconfiguration of this service, but I'm still concerned about the randomness of the error.
Damn you, Search Service!
