Strange Error Still: Failed to save user object
I realise this has been on the list a few times but I have to agree with
someone who posted a few months ago: this has never really been resolved
and normally ends up with lots of people saying things like 'it
probably doesn't really matter that much'... Is this definitely the case?
We are using the serialised objectdata to store user preferences and are
finding that, inexplicably, they seem to be 'forgotten' after about 24
hours although they are retained successfully during that time. We are
updating the setPerm hashtable and then calling an explicit .save() on
the user object. Our setup:
TDK2.1, win32 (dev) and linux (production - exception is thrown on both
platforms) on mysql
The logs are littered with this exception and it would be good to know
whether this is worth pursuing or not. Its not really ideal to have lots
of 'probably not very important' exceptions in the logs anyway...
Anyone resolved this?

...which would make sense as a Catalina problem, given all the class
loading fixes between 4.0 and 4.0.1.

Actually I may have given you a bum steer here. I just noticed that the
exception is not the same. The doUpdate part is but occurs on line 1631 of
BasePeer and is where it cannot find the class KeyDef in village.
Sorry,
David

Hi,
This was explained to me as a Tomcat 4.0b6 error. If you use the release
Tomcat 4.0.1 this does not occur. I have one PC with this version and
Turbine 2.1 but have not run it overnight so cannot confirm this.
Regards
David

Oops - sorry, forgot to give the details. The classic:

I haven't altered my session timeout from the default. Anyway, I'm
explicitly saving the user object after doing a setPermStorage.
