WebLogic 5.1 crashing on Solaris 8

[splitting10]

I have installed WebLogic 5.1 on Solaris 8 and it keeps crashing. It can be restarted but seems to keep crashing during times of high use (9-10am and 1-2pm). The java process for WebLogic will create a 90+ MB core file and terminate. The error messages from the stdout of the startWebLogic.sh script are ...


SIGBUS 10 bus error
si_signo [10]: BUS
si_errno [0]:
si_code [1]: BUS_ADRALN [addr: 0xf9453b9d]

Any suggestions?
