Just updated my SLES 11 SP4 to kernel-default 3.0.101-104.2 and now tomcat 7.0.78 core dumps immediately on startup.

I reverted back to the previous kernel-default 3.0.101.100.1 and the same tomcat runs normally.

# A fatal error has been detected by the Java Runtime Environment:

# SIGBUS (0x7) at pc=0x00007f1995d04ec3, pid=82488, tid=0x00007f19a79a2700

# JRE version: (8.0_131-b11) (build )

# Problematic frame:

# Core dump written. Default location: //core or core.82488

# An error report file with more information is saved as:

I have attached hs_err-vw-tomcat-324937.log

I am not sure what else to include here that would assist the kernel or tomcat developers

I am guessing this is related to fixes in the kernel for the Stack Clash
issues that came out recently; the fix is known to cause issues with
Java-based applications, like Apache Tomcat.

Some links to the Stack Clash issue and fix follow:
https://www.suse.com/support/kb/doc/?id=7020973

Also see:
CVE-2017-1000364
CVE-2017-1000366

I do not know of a fix for the new Java-related issue, but I'm looking and
sending this thread on to SUSE so the impact can be better-measured. They
are already aware of the issue and may have a fix already, in which case
I'll post back once I find it.

Good luck.

I have been informed by SUSE that this is a known issue with that kernel. A fix should be available shortly.
