At the end of last week I had two units from 2669 run and no credit showed up for either. One ran to 49%, and aborted with a fatal error. Console message was "Fatal error in MPI_Sendrecv: Error message texts are not available", which was not included in the log file. The second ran to 100%, then ran into an error transmitting the completed unit. I ran qfix and then did a -send all to see if any partial results would go out. Any records on these? In any case, qfix has left a clean queue, I have a new unit running on that machine.

Thanks for any info

Oh well, that is what I thought might happen. That kills my point accumulation for last week and hopefully the queue is clean now on that machine. Will see in another 12 hours or so.

Is your machine unstable? Have you looked into any procedures which might avoid errors like this in the future? It's hard to see a connection between the two errors except if something other that FAH is manipulating the work files. Perhaps you have an antivirus program that is quarantining some of FAH's files. NOD32 has been reported guilty of that. (It might be fixed in the latest version.) It's also pretty easy to exclude the FAH work directory from virus scans and that applies to any AV program.

This machine has been stable up until now running the 6.20 client for dozens of units, but I recently uninstalled that and installed the 6.24 client. NOD32 is not an issue, it is a Mac system running OS X. No AV software currently running, and I have done some other checks to see that the system has not been compromised with any malware. I suspect the first unit failing the way it did may have corrupted the work queue and caused problems when the second unit was started 12 hours later and finished in 24 hours.

I will know more in another 30-45 minutes, the current unit running is at 98% and should finish then. Running qfix does appear to have cleaned up the queue on this machine. As for the rest, I am still learning all the ins and outs of the version 6 console client, up until about 6 months ago I was just running version 5 on a couple older PowerPC Macs. Some of the postings in the forums here have been very helpful in getting things fixed and running. While I have been learning, I have been limiting the client on this Intel mac to runs with the "-oneunit" flag.
