What OS are you on? And what package did you download? ---

Hi, im running on Scientific Linux release 6.4 (Carbon) (64Bit) and downloaded kibana-4.3.1-linux-x64.tar. i know what the problem is: [root@XXX bin]# ldd node linux-vdso.so.1 =\> (0x00007fff17ff8000) librt.so.1 =\> /lib64/librt.so.1 (0x00007f7cb3f47000) libdl.so.2 =\> /lib64/libdl.so.2 (0x00007f7cb3d43000) libstdc++.so.6 =\> not found libm.so.6 =\> /lib64/libm.so.6 (0x00007f7cb3abe000) libgcc\_s.so.1 =\> /lib64/libgcc\_s.so.1 (0x00007f7cb38a8000) libpthread.so.0 =\> /lib64/libpthread.so.0 (0x00007f7cb368a000) libc.so.6 =\> /lib64/libc.so.6 (0x00007f7cb32f6000) /lib64/ld-linux-x86-64.so.2 (0x00007f7cb4159000) ``` libstdc++.so.6 => not found, trying to find a solution for that. the files exists: ``` lrwxrwxrwx. 1 root root 19 Jan 8 2015 /usr/lib64/libstdc++.so.6 -\> libstdc++.so.6.0.13 -rwxr-xr-x. 1 root root 930192 Mar 23 2015 /usr/lib64/libstdc++.so.6.0.13 but for some reason it doesnt see it in its rpath. any linux-savvy people could help out here? ---

Hi, Can you try this: ```auto ldconfig -p | grep libstdc ``` Do you see: ```auto libstdc++.so.6 (libc6,x86-64) => /lib64/libstdc++.so.6 libstdc++.so.6 (libc6) => /lib/libstdc++.so.6 ``` If not try running `ldconfig -v` and see if that fixes it. If not try doing: ```auto export LD_LIBRARY_PATH=/usr/lib64 ``` Then start kibana. ---

Hi, thanks for the reply, that would probably helped me to find the problem faster. the problem was, that for some reason, the lib file that was in the 64 bit folder was 32 bit: file /usr/lib64/libstdc++.so.6 /usr/lib64/libstdc++.so.6: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, stripped i copied a 64 bit lib file from a different node and it worked: ldd /var/opt/kibana/node/bin/node linux-vdso.so.1 =\> (0x00007fffb73ff000) librt.so.1 =\> /lib64/librt.so.1 (0x00007feac9923000) libdl.so.2 =\> /lib64/libdl.so.2 (0x00007feac971f000) libstdc++.so.6 =\> /usr/lib64/libstdc++.so.6 (0x00007feac9418000) libm.so.6 =\> /lib64/libm.so.6 (0x00007feac9194000) libgcc\_s.so.1 =\> /lib64/libgcc\_s.so.1 (0x00007feac8f7e000) libpthread.so.0 =\> /lib64/libpthread.so.0 (0x00007feac8d60000) libc.so.6 =\> /lib64/libc.so.6 (0x00007feac89cc000) /lib64/ld-linux-x86-64.so.2 (0x00007feac9b35000) ---
