            Bug ID: 151439
           Summary: JVM crash, [libjavascriptcoregtk-3.0.so.0+0x584e4d]
                    WTF::fastMalloc(unsigned int)+0x68d
    Classification: Unclassified
           Product: WebKit
           Version: Other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org

We have a long-running java-application that uses webkit via Eclipse SWT-bundles.
The browser shows html-pages with some images and javascript.

The application crashes in fixed intervals with this message in the jvm crash dump file
and we have monitored the system so that the memory used by the process seen by the OS
constantly grows but the JVM heap stays low. This points to memory reserved by 
libraries and webkit is the only non-jvm library we use.

Tested with different openjdk versions, java-7u79 to 7u85 with no effect.

Versions:
OS: Ubuntu 14.04.2 LTS
libwebkitgtk-3.0-0: libwebkitgtk-3.0.so.0.22.14
libjavascriptcoregtk-3.0-0: libjavascriptcoregtk-3.0.so.0.16.16
eclipse-swt-linux-gtk-x86: 3.103.1.v20140903-1947

Any advice would be helpful and we can provide more data if needed.
