Getting segmentation fault - Unable to start vxconfigd

Resolution
Only create the linux kernel max of 15 partitions on a disk. Then restart vxconfigd:
# /sbin/vxconfigd -k -x syslogEven though fdisk allows you to create more than 15 partitions on a disk after a reboot kernel will only be able to register 15 max partitions. If the user attempts to use a partition not registered in kernel they will get an error because the device partition does not exist in kernel.
Example:
# fdisk -ul /dev/sda Disk /dev/sda: 146.6 GB, 146695782400 bytes 255 heads, 63 sectors/track, 17834 cylinders, total 286515200 sectors Units = sectors of 1 * 512 = 512 bytes Device Boot Start End Blocks Id System /dev/sda1* 1012095 1220939 104422+ 83 Linux /dev/sda2 1220940 43166654 20972857+ 83 Linux /dev/sda3 43166655 286503209 121668277+ f W95 Ext'd (LBA) /dev/sda5 43166718 59954579 8393931 82 Linux swap / Solaris /dev/sda6 59954643 80935469 10490413+ 83 Linux /dev/sda7 80935533 101916359 10490413+ 83 Linux /dev/sda8 101916423 122897249 10490413+ 83 Linux /dev/sda9 122897313 124873244 987966 83 Linux /dev/sda10 124873308 126849239 987966 83 Linux /dev/sda11 126849303 128825234 987966 83 Linux /dev/sda12 128825298 130801229 987966 83 Linux /dev/sda13 130801293 132777224 987966 83 Linux /dev/sda14 132777288 134753219 987966 83 Linux /dev/sda15 136729278 138705209 987966 83 Linux /dev/sda16 134753283 136729214 987966 83 Linux /dev/sda17 138705273 140681204 987966 83 Linux Note: There are a total of 16 total partitions according to fdisk. Yet after there boot we can see the kernel can only see 15 total partitions.
