You're using an old version of the jna library, you might consider rebuilding from SVN sources (we'll be releasing an official 3.0 version soon. Wayne Meissner has improved the native layer on linux, although there's no guarantee any of the improvements are related to your issue.

Is the ServiceMix instability related to JNA or is that a separate issue?

I am using JNA inside a JBI BindingComponent running in ServiceMix 3.1.2 to access an external application via a C library.

Recently I got a JVM-crash for the first time in this setup, so I wonder what happened; I am running Kubuntu 7.0.4 (KDE 3.5.7, glibc 2.5, x86, 1GB RAM) - hope it's not my RAM...

Any tips are appreciated, as ServiceMix runs a bit unstable too, segfaulting without good reason in 25% of the cases (and giving no useful debug output beside: "-F- CDI: Caught UNIX signal Segmentation fault").

Thanks, Gregor
