Hi,

We're still using Slide 2.1 with Websphere 5.1 on Solaris and with J2EE store
and Oracle database.

Sometime, we get some failed requests along the following exception :

[11/8/06 15:49:40:675 MET]  1906210 WebGroup      E SRVE0026E: [Servlet

... remaining lines shows only webshpere classes

Request / response looks like this :

slide_filter.log:Servlet.Engine.Transports : 354, 08-Nov-2006 15:50:23,
unauthenticated, PUT, 500 "Internal Server Error", 5301 ms,
/xxxxxxxxxxxxx/0000000-00000012905--0000.xml



When we try to run some stress tests we get a lot of failed requests : With 20k
request we get about 100 failed requests (0.5%)
Our test application just run 20 threads that repeatedly put small (3kb) files
in different directories.

Any idea ?
Is there a risk of data corruption ?

Thanks,

Eric
