Restack particles I/O error

[daniel.s.d.larsson]

These errors are likely related to file I/O issues we are currently having with the instance due to too many open files.

70,000+ open files by NU-ref job

Multiple jobs on our instance throw file I/O errors. It seems we are hitting file system limits for number of open files. One NU-refinment job currently has more than 70,000 open files! Is that by design? The job is processing a large data set with 1.4M particles from 22k micrographs. The instance is running v. 4.7.0. In this thread, it is said that version v.4.6 increased the number of open files and that v.4.6.1 reduced that a bit.
