Project: 7611 (Run 2, Clone 39, Gen 319) runs very slowly

I am seeing this WU be very slow with a TPF of around 1:06:00 (1h+) where other WUs from this project have been running at an average of 0:7:26 on that machine. I don't believe anything else is interfering with it, but would reboot the machine to see if it helps, but I don't think it would. Here is the log file in the relevant area:

Probably one of these: Project 7611 (0, 23, 259) - High TPF

The root cause is a bug in the A4 core, and I've reported it to the correct people. I think that because this issue occurs in >.1% of WUs, it hasn't been a priority for our dev team, which is usually swamped.

This issue will be resolved eventually, but in the mean time please feel free to dump these WUs. Not only are the points bad, but when this issue occurs the returned WU is meaningless. Therefore it's beneficial for the science (and the donor) to dump the WU.

I do apologize and will bug the core dev team again. Please let me know if there are any further questions or concerns.
EDIT: perhaps the report above should be appended to the existing topic I linked to.
