Hello,

as I wrote in the topic, the client runs into an error:

Code:

maxPostSize on server side is 10.500.000 bytes. Up to 5MB files it works. More then 5MB I run into this error.

The client has -Xmx=256m

Any ideas what happens there? The client should have enougth memory for an 10MB file!

regards,
Michael Schmuck

...just checking...

Hmmm, sure that you are not uploading 50MB (instead of 5MB as you say...)??

Regards, Björn

sure !

this file fails for example:

7,87 MB (8.257.536 Bytes)

Hi,

I always though that using StringBuffer is the smartest way for concatenating strings - but indeed StringBuffer has some very obscure features inside, that cause the OutOfMemory when dealing with long strings...

We today will post a message in the Snippet-Area of the forum. Please look there for more details.

"Your" problem now is solved. The fix is part of the next update or can be sent on your request.

THanks + regards!
Björn
