This is just an update to put a permanent record of what's happening online.
There seems to be bugs in RH 7.2 on uni (and SMP) processor machines, I have not tracked them down, but no JVM seems to run stably on it. Upgrading to RH 7.3 definitely fixed our problems on our uni processor machines, but we still have a problem with the dual athlon (even when running a uni-processor kernel). This may be some weird SMP kernel/glibc bug, or it could be a hardware error (RAM has been swapped, but to no avail). So to anyone that comes across this using google, if you are running Redhat 7.2 and getting "Unexpected Signal : 11", then I would suggest you upgrade to Redhat 7.3. If you still get this problem on a dual processor machine after upgrading to 7.3, let me know, especially if you solve it. Unfortunatly, I don't know if my client can afford to buy another SMP machine just to find out if it will run java, so I might not be able to deploy to SMP :(( Thanks for all the suggestions from everyone, Regards, Craig O'Shannessy On Thu, 23 May 2002, Calvin Austin wrote: > > There is a very important patch to Redhat 7.2 SMP kernel, you need the > 2.4.9-31smp patch available under 'security patches' from redhat.com > > Unpatched redhat 7.2 SMP will create duplicate process ids.
