FileMaker 11 (Mac OS X) crashing when viewing SuperContainer webviewer

[MSBoswell]

I'm running SuperContainer 2.863 in StandAlone mode on an Xserve running Mac OS X Server 10.6.8 and FileMaker Server 11 Advanced (11.02.217). It works fine for all users (approx. 15) except one. The problem client is a Mac Pro running Mac OS X 10.6.8 and FileMaker Pro 11.0.4 (and all current OS updates including Java for 10.6 Release 8).

Sometime in the last couple of months (unsure of the exact date of appearance), the primary user began having the following problem: after accessing a layout that shows a SuperContainer webviewer and then leaving that layout. If the user tries to return to a layout with a SuperContainer webviewer, FileMaker hangs for about 10 seconds and then crashes.

Please see the attached crash report and system.log entries below. It appears to me that Java is crashing and then bringing FileMaker down with it.

I have cleared the Java cache many times, tried both orders for 32 and 64 bit Java environments, upgraded and re-installed FMP, upgraded SuperContainer (from 2.81), and re-installed the Java for 10.6 Release 8. However, nothing changes this behavior, and no other client has this problem. The problem is identical for multiple (all) users on the machine.

Does anyone have any idea how I can solve this problem on this machine?

Thanks,

- Martin
