I installed the SE Toolkit on several Solaris 10 hosts this week, and noticed that the se process was SEGFAULT’ing during startup:
$ /etc/rc3.d/S99orcallator start
Writing data into /opt/orca/nbm01/
Starting logging
Sending output to nohup.out
$ tail -1 /var/adm/messages
Aug 10 23:09:27 nbm01 genunix: [ID 603404 kern.notice] NOTICE: core_log: se.sparcv9[17571] core dumped: /var/core/core.se.sparcv9.17571
After fileing a bug report on the SE Toolkit website, it dawned on me that the issue wasn’t with the se program, but with the orcallator.se script that accompanied the SE Toolkit. Based on a hunch, I installed the latest version of orcallator.se from the Orca website, and that fixed my issue (and provided a number of additional useful performance graphs!). Hopefully this will help others who bump into this issue.
