Attempting to check in failed : No Open Slots, There are 0 Before Me

[IHCRCDan]

OS: Ubuntu 18.04
Fog: 1.5.7

Starting in the middle of last week, when we try to capture an image or deploy an image, the process starts okay, but right after the status message:

Send Method…NSF

We begin getting the following two errors in sequence:

Attempting to check in…Failed
No open slots, There are 0 before me. (In line for XX). The count begins at 0 or null, and then about every 10 seconds the count goes up by 5.

The clients and the server have been rebooted multiple times. The OS on the server and the version of FOG needed to both be updated, which have both been completed. I have found a couple of posts on this issue (https://forums.fogproject.org/topic/10169/storage-node-no-open-slots-there-are-0-before-me/3 and one that told me to make sure the WEB ROOT was set to /fog/), and neither one has been successful in resolving the issue.

We did not make any changes to the system or our network when this started to occur.

Any help would be appreciated.

@IHCRCDan What is “max clients” set to in the storage node settings? From what you wrote I assume you only have one FOG server, right?

@Sebastian-Roth you are correct. We do only have one server. You are pointing in the correct direction, as we had a maximum number of 10 clients selected and we had a number of tasks “stuck” in the storage activity group, even though they are no long in the task list. We have like 4 queued and 10 active. I was able to change the limit to 20 and now it is working fine. What I can’t figure out is how to remove the stuck queued and active tasks that are no longer valid.

First check the task view lists in the web UI. Do you still see them there?

If not you might try the database maintenance: https://wiki.fogproject.org/wiki/index.php/Troubleshoot_MySQL#Database_Maintenance_Commands
