In my case, I went and grabbed Java 1.3.1.09 from Sun's Java site, and installed that. Then I found that the segment fault I was seeing was caused by a bad patch to the Motif Libraries.

Sun's patch # 108941-56 causes many Swing calls in Java to fail, specifically the XtRemoveTimer call that LimeWire makes during startup.

The only cures for this problem is to revert back one patch level on this patch, if you saved the old patch data (I didn't). Or grab an old version of the library (/usr/dt/lib/libXm.so.4) from another system, which I was able to do. The library was from patch 108941-49, so we know that version works.

Once I replaced the libXm.so.4 with the old one, everything started working. I was able to get the LimeWire beta to connect, and have started using it. The internal media player also seems to work, and plays mp3 files just fine on my Solaris system.

I'm looking forward to getting the corrected patch, and to try the next version of LimeWire too.

Good Luck,
