[root at server ~]# cat /proc/meminfo | grep HugePages
AnonHugePages:         0 kB
HugePages_Total:   11776
HugePages_Free:    11776
HugePages_Rsvd:        0
HugePages_Surp:        0

Why it can be so? How to fix?


Yes, but i have bad past with this paramentr -XX:+UseLargePages.
-XX:+UseLargePages really make server unstable


java.lang.UnsatisfiedLinkError:
/usr/lib/jvm/java-7-openjdk/jre/lib/amd64/headless/libmawt.so: libcups.so.2:
cannot open shared object file: No such file or directory

While starting up server, i have this error ~3 times

And server runs now even with errors, but when i try to load something to the
buffer server die with the same log

And i asked one man from bukkit, message from him:
"I can't speak to archlinux, but I do know that sometimes there is a 'headless'
package for the JDK that includes the native libraries needed to run the JDK
headless (versus the ones that depend up the X libraries and the like). Its
possible that the base openjdk package java code refers to the JNI/native code
for the headless libraries, but doesn't itself include them....just a guess,
but it'd fit."
