Obscure behaviour

RT Users
1

Hi,

our RT 3.0.11 system runs fine mostly. But I have a special case with a
single browser on a single computer which is OmniWeb 5.1b4 (same
behaviour with 5.1b3) on Mac OS X Server. When I connect to the RT, I
get the error stated below. When I use Firefox on the same machine,
there is no error.

When I use the same version of OmniWeb on my laptop with Mac OS X there
is no problem. Also all other browsers work fine.

Any idea where this might point to?

Greetings
Tim

[snip] Any idea where this might point to?

Based on the fact that it only happens for once instance of a browser,
and the following snippets:

Out of memory during “large” request
[…]
code stack: vvvvvv
/usr/local/rt3/share/html/Elements/SetupSessionCookie:67
^^^^^^

…I’d guess that the browser is sending some funky cookies. Try
clearing the cookies on the browser in question, or watching the
browser’s traffic to see what cookies it’s actually sending to the
server.
