Hi, I have set the memlock limit to unlimited in /etc/security/limits.conf
[devel...@localhost apache-cassandra-0.7.0-rc1]$ ulimit -l 0 Running as a non root user gets me a Unknown mlockall error 1 [devel...@localhost apache-cassandra-0.7.0-rc1]$ bin/cassandra [devel...@localhost apache-cassandra-0.7.0-rc1]$ INFO 14:52:47,777 Heap size: 1060569088/1061617664 WARN 14:52:47,884 Unknown mlockall error 1 If I run as root user [devel...@localhost apache-cassandra-0.7.0-rc1]$ sudo bin/cassandra [devel...@localhost apache-cassandra-0.7.0-rc1]$ INFO 14:53:43,776 Heap size: 1060569088/1061617664 INFO 14:53:52,510 JNA mlockall successful I am running linux Linux localhost.localdomain 2.6.18-194.17.4.el5 #1 SMP Mon Oct 25 15:51:07 EDT 2010 i686 i686 i386 GNU/Linux Java [devel...@localhost apache-cassandra-0.7.0-rc1]$ java -version java version "1.6.0_22" Java(TM) SE Runtime Environment (build 1.6.0_22-b04) Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode) What else can I provide to determine this issue, or is my centos kernel just not capable?? Perhaps only more recent kernels are supported outside of root?
