Línea de trabajo

Reproduce under flux alloc -N4 with the issue's repro.sh: start, end, then start again. Read fluxmgr_add_to_kvs in fluxmgr.c around lines 84-141, especially the existing-namespace branch and the failing KVS commit; follow how spindlefemgr.c setup and launch_flux.cc spawnDaemon use that namespace. Done means the second --start-session succeeds after --end-session, with no "Internal error while spawning spindle daemons".

Descripción

Using the Flux resource manager, if running spindle --start-session immediately after spindle --end-session results in an "Internal error while spawning spindle daemons" and the session fails to start:

fluxuser@node-1:~$ flux alloc -N4

ƒ(s=4,d=1) fluxuser@node-1:~$ cat repro.sh
#!/bin/bash
spindle --start-session
echo "first --start-session exit $?"
spindle --end-session
echo "--end-session exit $?"
spindle --start-session
echo "second --start-session exit $?"

ƒ(s=4,d=1) fluxuser@node-1:~$ ./repro.sh
first --start-session exit 0
--end-session exit 0
Internal error while spawning spindle daemons
second --start-session exit 0

For the first, successful, session, the logs show:
