Yeah,and I found the reason. Seems that (at least for the mysql procedure get_parent_limits) mySQL 5.7.30 returns NULL where mySQL 5.7.29 returned an empty string.
Running mySQL < 5.7.30 is a bad idea, as there exist two remotely exploitable bugs with a CVSS score of 9.8!
(see also https://www.cbronline.com/news/oracle-security-patches) So, this needs to get fixed soon. Best Marcus Am 06.05.2020 um 20:30 schrieb Dustin Lang:
Hi,Ubuntu has made mysql 5.7.30 the default version. At least with Ubuntu 16.04, this causes severe problems with Slurm dbd (v 17.x, 18.x, and 19.x; not sure about 20). Reverting to mysql 5.7.29 seems to make everything work okay again.cheers, --dustin
