ROracle gives segfault on load--on only one server

Hello:

We have a datacenter with many servers all running Ubuntu 16.04 (Xenial) which are used interchangeably to run our production processes. On only one of these servers, we cannot load the ROracle software. Here is the error that occurs on that server:

> library(ROracle)

Loading required package: DBI

> dbDriver("Oracle")

 *** caught segfault ***

address 0x7f8fffefb000, cause 'invalid permissions'

Traceback:

 1: .Call("rociDrvInit", drv@handle, interruptible, extproc.ctx,   unicode_as_utf8, ora.attributes, PACKAGE = "ROracle")

 2: .oci.Driver(.oci.drv(), interruptible = interruptible, unicode_as_utf8 = unicode_as_utf8,   ora.attributes = ora.attributes)

 3: findDriver(drvName)(...)

 4: dbDriver("Oracle")

 5: dbDriver("Oracle")

Possible actions:

1: abort (with core dump, if enabled)
