Don't know if it helps but I found a number of these in my system log when these all failed.

cmdock[36125]: segfault at 5634063e8400 ip 00007f1fa00126d6 sp 00007ffe7b743ba0 error 4 in libcmdock.so.0[7f1f9fd52000+45b000]
cmdock[36541]: segfault at 55adf716bb30 ip 00007fb85fe95539 sp 00007fffc47c7d00 error 4 in libcmdock.so.0[7fb85fb46000+45b000]
cmdock[36441]: segfault at 557dcd3dace0 ip 00007f99ecbb66d9 sp 00007ffc3a8657a0 error 4 in libcmdock.so.0[7f99ec8f6000+45b000]

I won't paste all 40 of them here but they all end the same "error 4 in libcmdock.so.0[************+45b000]'

Yes computer 23025 is one I am questioning. It is a 12c/24t Xeon with 32G of memory, and it was not running anything else demanding at the time, so I doubt memory was an issue, although I did add memory recently. It continued to run some tasks successfully even after the 40 that failed. These all failed within a very short time period. I moved it to another project and it is running fine there, which is why I as questioning if there was something up with the tasks that failed. If it is some system issue I am not sure what to look for, I have not restarted the OS or BOINC since this occurred. I will try moving work back to it and see what happens.

I have been running non stop since 11/22 with no issues and suddenly 40 tasks fail all at once. Bad batch? Not much to see in the error log.
