ISCLOG Error

I received an ISCLOG errors in my IRIS container, and the processing is very slow because of that. How to solve this problem?

[Utility.Event] ISCLOG: SuperServer Super Server job slave failure ns=%SYS rtn=%SYS.SERVER
[Utility.Event] SuperServer failed to start slave server
 

Product version: IRIS 2021.1

I'd look at the other logs on the system. That error indicates that a job can't be spawned, so the question would be why?

Maybe the performance problem is rooted in that same reason.

edit: you may want to consider opening a WRC case for this if you can't find evidence of a problem.

We also received this alert last Friday. We had to perform a failover due not able to troubleshoot since it was affecting our Portal and Interface connections. What was the reason, did you guys ever find out?

What version are you on?

Hi,

You should consider to check other is errors.

Usually happens when /tmp is full, when the disks are slow (top command and look for "wa" statistic), check system logs and, may be, apache limits.

It's saying that he can't create a job, so you are short on some resource.

Or the antivirus...
