Hi All
I am building jdk7u on linux and it's stuck in images build (for almost an hour). Turns out native2ascii uses too many CPU:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
23569 ******* 20 0 9436 676 540 R 54.4 0.0 15:56.11 native2ascii
The machine is
Linux ******** 2.6.39-400.21.1.el6uek.x86_64 #1 SMP Thu Apr 4 03:49:00 PDT 2013 x86_64 x86_64 x86_64 GNU/Linux
Red Hat Enterprise Linux Server release 6.4 (Santiago)
The command (according to ps -f) is
/java/re/jdk/1.6.0/archive/fcs/binaries/linux-amd64/bin/native2ascii -J-XX:-PrintVMOptions -J-XX:+UnlockDiagnosticVMOptions -J-XX:-LogVMOutput -J-Xmx512m -J-Xms512m -J-XX:PermSize=32m -J-XX:MaxPermSize=160m -reverse -encoding UTF-8
I can kill it (actually, twice) and the build goes on and succeeds finally. Has anyone seen the same problem?
Thanks
Max
