Alexey, Greg,
We're in the middle of deploying quite a large frontend application on
Tomcat 4. We'd prefer to deploy on J2SE 1.3/FreeBSD, but we're getting
SIGBUS errors. Currently we're using these versions:
* Tomcat 4.1.24
* JDK 1.3.1p7
* FreeBSD 4.7-STABLE (Compiled @ 2002.11.18/14:56:20 CET)
* x86 SMP system (Dual P4, I think)
I see a number of alternative solutions:
* Upgrade to FreeBSD 4.8 (I remember there were some Java-related
improvements after Nov 2002, right?)
* Upgrade to JDK 1.3.1p8
* Set MAXUSERS to 0 in the kernel config file and recompile and install the
kernel (I remember this solved some native JDK problem in the past)
* Use a different J2SE VM (I don't really want to do this)
* Examine the core file to see what exactly went wrong
Any suggested approach?
Would any of you be able to examine the contents of this core file? I have
no experience with that sort of thing whatsoever :(
This is the head of the error message in the log file:
SIGBUS 10* bus error
