No my native Linux 6.23 smp client install does not have a cpuinfo.txt file only client.cfg and unitinfo.txt so that must be something to do with nofreds. As for your clients installed from workstation iso not having the problem I don't think that is the answer. I have had the log function work fine on some clients in VMware on one wu and on the next it would exhibit the problem so the problem is intermittent. I noticed the problem more on a2 core wu's than a1 core wu's but I had seen it on both and I have had both complete a wu without the error so its very hard to isolate the cause.
