[Mesa-users] Failure to write kap_data for one user on a system

[Francis Timmes]

hi ben,

a few perhaps silly questions:
1) does the machine have enough disk space and/or memory?
2) are multiple users trying to write to the same cache directory at the same time?

this thread reported a similar issue when writing eos data

https://lists.mesastar.org/pipermail/mesa-users/2018-February/008753.html

and its solution / debug steps might be useful.

For some reason, one user within our group cannot write some opacity data from the default cache, particularly when the star begins to burn helium (regardless of how degenerate the core is) and when it enters the final cooling track. I have not experienced this problem and others have told me that they haven't either. An example of the given error is below:
