1.5.0 RC9 - Scheduled tasks view "disables" the web UI

[george1421]

When you open the scheduled tasks view the web gui stops. When that happens please inspect the apache error log via the linux console on the fog server. The apache error log is located in /var/log/http directory. Just tail that file and post the error here, please.

I get - before I start the scheduled task even, this error:

[Fri Sep 15 07:38:47.258945 2017] [:error] [pid 4691] [client 192.168.43.88:34096] PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 32768 bytes) in /var/www/html/fog/lib/fog/fogcontroller.class.php on line 261, referer: http://fog.lfdw.local/fog/management/?node=host&sub=edit&id=82

After I start a cron job the web gui says it saves fine, but I get the same above error message in /var/log/httpd/error_log.

Then when checking in tasks -> scheduled tasks that stops the web gui from working but in the log file nothing else happens.

[Taspharel]

I just noticed the server time is off by an hour, maybe that plays into this?

Edit: Naw … Same problem, trying to check the scheduled tasks freezes the web GUI

[Taspharel]

I edited the php.ini file as suggested here: https://forums.fogproject.org/topic/6800/php-fatal-error-allowed-memory-size-of-134217728-bytes-exhausted-fog-1-2-0-missing-fog_memory_limit/2
in order to get rid of the above error.

Now that error doesnt appear anymore in the error_log

But nothing else does either and the web gui still doesnt work

@Taspharel Hmmm, nothing in the error logs anymore?! Well then we need to see what you have in the database. Open a terminal window on your FOG server (find the password in /var/www/html/fog/lib/fog/config.class.php

shell> mysql -u root -p
Enter password:
Welcome to...
...
mysql> use fog;
mysql> SELECT * FROM scheduledTasks\G
...
mysql> quit

Post what you see here in the forum either as text or picture.

[Taspharel]

Okay, here we go.

Doing this first thing in the morning yields:

MariaDB [fog]> SELECT * FROM scheduledTasks\G
*************************** 1. row ***************************

stName: Deploy Task

After that I scheduled a task, went to tasks view and waited for the freeze, after it shows the additional task:

@taspharel This only happens on scheduled tasks?

[Taspharel]

Just checked: Yes, all the other menu points in the tasks menu open correctly.

[Tom Elliott]

Do you do a lot of scheduled tasks? It sounds almost as if there’s a lot of delayed/cron jobs in the queue, based on what I’m hearing.

[Taspharel]

No, was the first time I tried it.

And according to the mysql thing there should only be 3 active scheduled tasks?

I just ran the mysql cleanup commands from the fog-wiki … problem remains.

[Tom Elliott]

I’m still unable to replicate this issue, would you be willing to install Working branch and see if it’s fixed in there for you? It may have been a Javascript thing that I fixed later in working.

[Tom Elliott]

This still really feels like something just isn’t jiving properly. I’m going to mark this solved as 3 weeks without any more word is a long time, I know I only responded yesterday and all. I’m unable to replicate, and I’m not sure that all people are seeing the problem. If this is still a problem, please let us know.

I’d also recommend jumping on working branch just to see if there’s something I’ve fixed and didn’t realize it.

[Taspharel]

Updated to working branch, same error still appears.

I don’t need the scheduled tasks urgently in any way, so just forget it if its working for everybody else

Thanks for your help!

I know this is quite an old topic, but we ran across this on the latest version of fog and I wanted to share my solution.

What ended up working for me was to get into the database console with mysql -u root

I then selected the fog database use fog;

Then I listed out the tasks SELECT * FROM scheduledTasks;

In my case the most recent record had an stID of 13, so I dropped that row, which fixed the issue DELETE FROM scheduledTasks where stID = 13;. After that the scheduled tasks menu loads fine.
