Hi all

Since the upgrade a couple of my toolkit servers are not getting their pscheduler tasks any more. Other servers in the mesh are fine. I fixed limits.conf on all of them. Here are the outputs on one of the problematic servers.

[root@ps-14-ldn-tele pscheduler.d]# psconfig pscheduler-stats
Agent Last Run Start Time: 2023/04/21 11:26:28
Agent Last Run End Time: 2023/04/21 11:26:31
Agent Last Run Process ID (PID): 6043
Agent Last Run Log GUID: 982BCE5E-E026-11ED-AAE4-70F37E5E890A
Total tasks managed by agent: 0

[root@ps-14-ldn-tele pscheduler.d]# psconfig remote list

]

[root@ps-14-ldn-tele pscheduler.d]# pscheduler  troubleshoot
Performing basic troubleshooting of ps-14-ldn-tele.

ps-14-ldn-tele:

  Measuring MTU... 65535 (Local)
  Looking for pScheduler... OK.
  Fetching API level... 5
  Checking clock... OK.
  Exercising API... Archivers... Contexts... Tests... Tools... OK.
  Fetching service status... OK.
  Checking services... Ticker... Scheduler... Runner... Archiver... OK.
  Checking limits... OK.
  Idle test.... 6 seconds... Finished... Checking archiving... OK.

pScheduler appears to be functioning normally.

I can see some tasks are available on the web interface:

https://ps-14-ldn-tele-10g.perfsonar.ac.za/pscheduler/tasks

I don't see anything funny in the log files:

Any ideas ?
