Oh, and we've since then tried with jamvm 1.4.5 and classpath 0.93.

Hi again,
Noone has ever seen this? This is currently a showstopper for us. Any kind of feedback would be appreciated.

Hi,
 
jamvm (1.4.4) works great for us except that it hangs about 1 out of 10 startups. When this happens CTRL-C can't be used to terminate the process and QUIT does not work to get a thread dump on those occasions.
CPU load is next to nothing when this happens.
 
Platform:
PPC MPC5200
Linux eldk 2.1, gcc 2.95.4
Also tried to compile with disable-int-thread disable-int-direct, no difference
Classpath version: 0.92
 
Attached are logs when it works fine and when it hangs with verbose jni and strace information. Both are zipfiles containing one text-file each, but with an extra suffix to get around the zip-file filter on the sf-mailing lists.
 
Does anyone have any ideas what could be the cause of this, or more things for us to try?
