 Description   
I have a large document cached (about 3.2MB on disk) on a one server instance running in Windows 2008R2. When I attempt to bring this document up in the web admin console, or to create a view from it, it freezes and eventualy crashes the web browser. This is happened whether the document is json or binary, and in Chrome and IE9. Retrieving the document through the .NET client works fine however.

Farshid,

Can you assign this issue to someone on your team since I don't have access to a windows machine. If it is reproducible then do we want to fix it for 2.0 or move it to 2.0.1.

can you please try loading this document via chrome on linux ?
Comment by Mike Wiederhold [ 05/Nov/12 ]
Iryna,

This bug is filed against Windows, but it would be good to double check linux too.

Please let me know if you need more information

happens for blobs and for json.

per bug-scrub mtg, options...

- check if doc too large and not display or display only 1st N lines
- key priority is to ensure the console does not crash

do not want a server-side fix; instead client-side fix is sought at this point

keeping this open for now for a day or so to see if we can get a fix
Comment by Aleksey Kondratenko [ 06/Nov/12 ]
Hi.

Try to fix this one.

Basic idea is _before_ parsing document as json, check if it's bigger than 2-3 kbs and if it is just show some reasonably nice error.

Something similar can be done for those base64-encoded non-json docs if possible

if not fixed by Friday, it's not in for 2.0.
Comment by Steve Yen [ 09/Nov/12 ]
