v25.05.4

Changes in 25.05.4

• scontrol/sacct/sacctmgr - Prevent hitting a double free when slurm is compiled with --enable-m
  emory-leak-debug and using the --json or --yaml options.
• Prevent possible truncation of the CPU_IDs list in "scontrol --details show job" on high-core-
  count systems.
• slurmd - Fix potential memory leak when incoming RPC is rejected or fails to unpack successful
  ly.
• Demote certain plugin loading "error" messages to "debug" messages. This prevents unnecessary
  errors from being logged when slurmrestd tries to load the tls/s2n plugin to handle https reques
  ts. Failures to load any other plugins will still result in informative "error" messages being l
  ogged.
• Respect time_min_as_soft_limit when calculating the projected job end time.
• Fix a regression added in 25.05.2 that broke compatibility with PMIx v2.x through v3.1.0rc1.

  partitions field would be incorrectly populated.
• Fix regression that caused slurmctld to wait forever on shutdown until all powersave scripts c
  ompleted. Now the slurmctld waits up to 10 seconds, as documented.
• Improve consistency of invalid node name errors.
• Prevent potential memory corruption while forwarding messages that require addresses to be pac
  ked.
• slurmctld - Increased the default maximum number of incoming connections from 50 to 512 as con
  figured in slurm.conf with SlurmctldParameters=conmgr_max_connections=512 to reduce amount of co
  nnections getting deferred responses.
• Avoid allowing one extra connection above the configured conmgr_max_connections limit.
• Docs - Change man page footer to display the current Slurm release instead of the last-changed
  "Month Year".
• Docs - Remove "Last modified" dates from HTML documentation.
• slurmstepd - Fix deadlock when PMIx receives an event during step termination, which caused st
  uck stepd processes after job completion.
