Similar problem here. Arima HDAMA, dual 246, 8 gig, LSI Megaraid SCSI,
and SLES 8.
Blackdown 64 bit 1.4 JVM (others tried, but too numerous to mention)
Jakarta-Tomcat 4.1
Apache, JSP, servlets, etc.
Now working, but still gets java segfaults in /var/log/messages (enought
that it is now linked to a file on a partition with more space). We have
been working on this for a couple of months, but still do not have a fix.
Some things have helped:
ulimit -s 2048 (for the shell starting Tomcat)
Memory reduced in Tomcat => -Xms256 -Xmx 1024 (as far as I know this
should do nothing in 1.4, but it seems to help)
Al, please stay in contact as to what you find out on this. Our
application is running, but I want to get rid of this problem.
Regards,
Bob Thilsted

Hello; We're having problems with java on our dual opteron 242 box. The box has 2gb Ram, and a Tyan 2885 mb. We have an application that runs in jboss 3.2.3. We installed a clean copy of 64 bit Suse 9.1 and setup our application. The application started dying in various ways which we traced back to the following errors appearing in /var/log/messages: May 17 13:23:27 dev5 kernel: java[5474]: segfault at 0000000000000004 rip 0000000057ea7300 rsp 000000008127f938 error 4 May 17 13:23:27 dev5 kernel: java[5474]: segfault at 0000000000000004 rip 0000000057f95f6a rsp 0000000081280040 error 4 May 17 13:23:29 dev5 kernel: java[5474]: segfault at 0000000000000004 rip 000000005800363e rsp 000000008127f558 error 4 May 17 13:23:29 dev5 kernel: java[5474]: segfault at 0000000000000004 rip 000000005800d8ca rsp 000000008127ed60 error 4 We even tried running jboss without our application deployed and got the same errors out of the jboss jmx-console. We have been running 64 bit Suse 9.0 before this; we had tried some of the preproduction 2.6 kernels for that and got similar errors. The standard 2.4 kernel(201) works without those errors, although the last 2 builds (209 and 215) have caused some less severe java out of memory errors. We've tried 3 different JVM's and got the same errors, the JVM's are the Blackdown.org 32 and 64 bit rc1 versions and the Sun 1.4.2_3. All the version info and processor info are below. Any idea where I can go for some help with this?
