buffer is found. Bug 2576 What happened was a function was doing a double read lock which isn't awesome to begin with, but not really horrible (if all you are doing is read locks anyway). The problem was after the first lock was locked a different thread was going for a write lock and so when the second read lock came in it created deadlocked.

Avoid possibly aborting srun that gets simultaneous SIGSTOP+SIGCONT while creating the job step. The result is that the signal hanlder gets a argument (the signal received) of zero. Here's a log, window 1: $ srun hostname srun: Job step creation temporarily disabled, retrying srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 18 srun: I Got signal 0 srun: Cancelled pending job step Window 2: $ kill -STOP 18696 ; kill -CONT 18696 $ kill -STOP 18696 ; kill -CONT 18696 $ kill -STOP 18696 ; kill -CONT 18696 .... bug 2494

The uid is used as part of the hash function, must remove old reference and recalculate if it may change, otherwise _delete_assoc_hash will not find it again when the association is removed, causing slurmctld to segfault. Bug 2560.

Previous gang scheduling logic maintained information about resources originally allocated to the job and made scheduling decisions on that basis. bug 2494

This will improve ability to diagnose problems if the srun is killed by a signal.

time. https://bugs.schedmd.com/show_bug.cgi?id=2547 The code just wasn't fully baked before and was probably written before a lot of the other supporting code was done i.e assoc_mgr_set_assoc|qos_tres_cnt were done specifically for this kind of thing. Many of the usage structures weren't realloced either as well as the tres_cnt local to each qos and assoc wasn't updated. So all in all pretty bad code - bad Danny. This makes sure all this sets up and no memory corruption happens.

burst_buffer/cray plugin: Prevent a requeued job from being restarted while file stage-out is still in progress. Previous logic could restart the job and not perform a new stage-in. bug 2584, comment #45

Fix Cray NHC spawning on job requeue. Previous logic would leave nodes allocated to a requeued job as non-usable on job termination. Specifically, each job has a "cleaning/cleaned" flag. Once a job terminates, the cleaning flag is set, then after the job node health check completes, the value gets set to cleaned. If the job is requeued, on its second (or subsequent) termination, the select/cray plugin is called to launch the NHC. The plugin sees the "cleaned" flag already set, it then logs: error: select_p_job_fini: Cleaned flag already set for job 1283858, this should never happen and returns, never launching the NHC. Since the termination of the job NHC triggers releasing job resources (CPUs, memory, and GRES), those resources are never released for use by other jobs. Bug 2384

An error in slurmconfgen_smw.py caused it to parse the nic as the nid. On some systems those values differ, causing the generated slurm.conf file to be incorrect. Bug 2532.

In particular, it seems that MariaDB has changed the default for innodb_lock_wait_timeout has been lowered which can cause issues for the various rollup processes on systems with high job counts.

slurmstepd to close potential open ones. It was pointed out the slurmd using acct_gather_energy/ipmi links to freeipmi which could possibly open /dev/ipmi0 without the close on exec flag set as root while launching a step leaving it open in the users app. What this does is sets the flag on the first 256 to mitigate the concern. Reported by Maksym Planeta. Bug 2506
