For the last few days, our server has gone down and when I restart it and drill down to the VDS reflections they all have red stop signs and the message ‘Multiple attempts to build reflection failed, will not reattempt.’. Yesterday I followed these instructions https://community.dremio.com/t/error-too-many-open-files/2003 but apparently they didn’t work because we have the same problem again today.
Has anyone else had this issue?
Hi @summersmd
Were all the failures due to max open files? Can we have some profiles of failed jobs?
Thanks

All of the failures were due to max open files. How do I produce profiles of failed jobs?
What did you increase your max open files to? Have you configured systemctl? There is a bug in Linux that when ulimit change does not take effect if service is configured via systemctl
