[slurm-users] error: DBD_SEND_MULT_MSG message from invalid uid 9920

[Michael Smith]

I’m new to SLURM and attempting to setup a new installation.  I’ve built the 20.11.2 tools on CentOS 7, and now I’ve got the MariaDB running but the slurmdbd log file is full of:

The “slurm” user is a local user – checked across all machines and they all report:

[1271] root:yyzeon10 /home/soc_tools/slurm/logs > id slurm
uid=9920(slurm) gid=9920(slurm) groups=9920(slurm)

Our slurmdbd.conf file is fairly generic:

# Slurm Database Configuration
AuthType=auth/munge
SlurmUser=nobody
DbdHost=localhost
DbdPort=6819
StorageHost=localhost
LogFile=/home/soc_tools/slurm/logs/slurmdbd.log
StorageType=accounting_storage/mysql
StorageLoc=slurm_acct_db
#StoragePort=

# Account information
StoragePass=mysql_slurm_password
StorageUser=slurm

#
PurgeEventAfter=1month
PurgeJobAfter=12month
PurgeResvAfter=1month
PurgeStepAfter=1month
PurgeSuspendAfter=1month
PurgeTXNAfter=12month
PurgeUsageAfter=24month

#
ArchiveEvents=yes
ArchiveJobs=yes
ArchiveResvs=yes
ArchiveSteps=no
ArchiveSuspend=no
ArchiveTXN=no
ArchiveUsage=no


#
#DebugLevel=info
DebugLevel=debug5

Any suggestions on where I should look for a problem?

Thanks,
Michael
