I have a web app that uses a Java Applet for various functions like finding network devices through multicast, as well as combining XML and a xsl-fo template for printing.

Recently most of my users (an intranet web app) upgraded to Java 7. Ever since a small proportion of my users (5-10%) are having random crashes in IE with the exception code being

Exception code: 0xc0000005


The fun part is that the 5-10% all seem to be in a few offices where 50% of the users get it and 50% don't.

I have had the users run SFC /scannow to determine if there are any corrupt system file's and some users are fixed after that, but most aren't.

Any idea's?

I agree. HS_err files aren't created. Event Viewer says it is j2piexp.dll that caused the seg fault. Users are saying they aren't doing anything that would be using the applet at the time. We use LiveConnect to communicate back and forth between the applet and the html page. – Tristan Jan 7 '13 at 18:18
I can duplicate crashes using J7u1 just by refreshing any page with an applet. It may take a while but eventually I will crash IE. That crash is in jvm.dll though, and only happens for Java 7 u1. I have gotten some users to upgrade to java 7 u9 or u10 and they are still experiencing it. – Tristan Jan 7 '13 at 18:20
Some users have switched back to Java 6u 38 and are also getting crashes. Any idea's on things I could try? – Tristan Feb 5 '13 at 15:49
