> Hi Erik,
> We are not using xforms:upload at all, even our submission is default
> (replace="all") . We found that our  java processor going to a long  
> loop
> about 40,000+ at that time we found more warning messages as "another
> submission requires a second pass ...". ( we changed our java code  
> so solve
> this)
>
> We used xforms-state-handling as "server" resulting in repid  
> increase of
> WEB-INF/exist-data size daily 1GB and some of the threads are  
> blocked for
> some seconds result in system very slow.
>
> We modified xforms-state-handling as "client" now and system working  
> well
> now ( no exist-data increases no slowness now)
> Thanks for your support.
