Just rebuilt my linux machine and on every workunit I am getting the following:

<core_client_version>6.2.15</core_client_version>
<![CDATA[
<message>
process exited with code 22 (0x16, -234)
</message>
<stderr_txt>
execv: Permission denied

</stderr_txt>
]]>

World Community Grid is working fine however so I am not sure what's going on. Any ideas?

Hello JohnB175,

The BOINC FAQ Service gives some information about the error code 22 (0x16, -234):
Link to Boinc FAQ service.

However it is somehow strange the error only occurs on Rosetta Wu's.
You might as well consider to post on the message board: number crunching, since the message board is better read then the questions & answers.

Good luck,
