Regarding your question : Matthew Ling wrote: I am using IBM SDK 1.4.2 (build cxia321420-20040626) with Red Hat EL AS 3.0 (kernel version 2.4.21-15.ELsmp , gcc version 3.2.3 20030502) . I had a few sporadic JVM crashes. All crashes happened inside the same offset of module libjitc.so with signal 11 (i.e. segmentation fault). My questions are as follows - Is SDK 1.4.2 certificated to run in Red Hat EL AS 3.0 since most posting seems to be related SDK 1.4.1? yes it is certified, Check the URL http://www-106.ibm.com/developerworks/java/jdk/linux/tested.html - Will LD_ASSUME_KERNEL=2.4.19 fix the problem? May but, but this setting will make JVM to use Linux threads instead of NPTL which is a new feature in RHEL3 - What is stable version of SDK for Red Hat EL AS 3.0? The lastest GA version available on JIM site. Thanks, Matthew One of the RH libraries got changed to eliminate several bugs. These had been coded around in early 1.4.2 versions. As a result the IBM 1.4.2 did strange things on RH. If you update to the latest levels it should fix your problem. Back to top Rupesh B.

Nick Burch wrote: Quote: I'm trying to use 1.4.2 build 2.2 on my new em64t system (I've downloaded the amd64 version of the SDK). Running java works fine, but when I try to run javac, it dies horribly: Unhandled exception Type=GPF vmState=0x00000000 Target=2_20_20050224_1940_LHdSMr (Linux 2.6.8.tbx) CPU=amd64 (4 logical CPUs) (0x7d558000 RAM) (full core file attached). This is running on the amd64 build of debian testing. Is this a known problem? The sun 1.5 sdk (for amd64) works fine Thanks Nick Back to top Rupesh B.

I don't think that should be an issue. Incase you are still facing the same problem could you please pass on the testcase to me so that I can check the same at my end. Thanks, Rupesh.
