Have you checked what version of Linux your host is running? Some plugins need to be recompiled to work with some versions of Linux in past experience so you should check that out. Also you should contact your host about it, as this is what is defined in wikipedia.

A segmentation fault (often shortened to segfault) or bus error occurs when the hardware notifies a Unix-like Operating system about a memory access violation. Then the OS kernel sends a signal to the process which caused the exception. By default the process receiving the signal dumps core and terminates. The default signal handler can also be overridden to customize how the signal is handled.
