You probably built slurm with immediate binding instead of lazy binding. Check the tags in the plugin for BIND_NOW:
$ readelf -d /usr/lib64/slurm/select_cons_tres.so | grep BIND_NOW
If you find that tag, relink slurm with lazy binding instead, i.e. do not use any form of "now" linking, e.g. -Wl,-z,now.Note that the linker will honor the last directive seen on the command line, so simply appending -Wl,-z,lazy to the endshould suffice.
