We see that there is an issue with our NaCl Client (at http://nacl.foldingathome.org), with donors seeing this error:
Warning: Unexpected response to AS assignment request: error,DB ERROR: IO error: log.leveldb/016519.ldb: Too many open files
The server is being overloaded and our sysadmin team will take a look at it when they get back on Monday. Long term, it looks like it’s time for us to upgrade the server this is running on since it’s getting overloaded. We have been moving to get new servers ready for this and so getting to that should happen in about a week (servers are here and the sysadmin team has been working to getting them ready for their new roles in FAH).
