Work Log Calendar + Time to SLA Plugin = Trouble


When Time to SLA Plugin ( is active, logging on Issues with a high number of log entries is not possible anymore. The "Log Work" window does not dissappear after pressing "Log". Pressing "cancel" after a few minutes closes the window. No entry in the calendar. Shortly afterwards, an error message appears: "Internal Server Error".

If I log work on the same issue via JIRA (More-Log Work), then I get the message: "The call to the JIRA server did not complete within the timeout period. We are unsure of this operation. Close this dialog and press refresh in your browser"

If Time to SLA Plugin is deactivated, these errors do not occor. Please can you test this on your system and fix this issue?

Many thanks

Hi Barbara!

Just installed Time to SLA Plugin and reproduced exactly the same behavior for issue that has about 1100 wroklog entries.

The problem is caused by Time to SLA Plugin rather then by Work Calendar plugin. For time logging Work Calendar relies on JIRA REST API and Time to SLA "kills" reporting for issues that match defined rules and have many worklog entries.

To be sure I uninstalled Work Calendar and tried to report time for issue with 1100+ worklogs through JIRA (More-Log Work) and it hanged my instance.

Time to SLA team, could you please check this.

@Volodymyr: Wow, thank you for this incredibly quick test result and reply on a sunday evening!

@SLA Team: Hope you can fix this, thank you in advance

@SLA Team: please answer

Hi Barbara, Volodymyr

I am really very sorry that I could not notice this question.

Are you using the latest version TTS? TTS had performance issues and I think you will not face the same problem with the latest version. Also, there will be other improvements not to effect JIRA issue transitions badly.

Hi @Tuncay Senturk , On September 27 when I did the test I used the latest version.

Hi @Tuncay Senturk [Snapbytes]! I am currently testing JIRA 6.4.12 with TTS 5.6.0 and Work Calendar 2.5.6. On the test instance logging onto large issues works fine (takes 2-3 seconds) :)

After further Tests with more Users: Logging onto Issues with a high number of log entries is still fast 90% of the time, but sometimes still takes 20-40 seconds. Happens sporadically and seems to get better if the User has logged onto the same issue before.

@Volodymyr Krupach Please can you gray out the "Log" Button when it has been hit? If the logging takes longer, Users keep clicking the button because they think it did not work. That way they create multiple work logs

Hi @Barbara Kohlroser , this will be part of the next release.

Excellent @Volodymyr Krupach, thanks!

Forgot to mention @Tuncay Senturk [Snapbytes] - please see my comment from yesterday 1:20 PM

Hi all, I am watching this thread and also working on reproducing the problem. I also tried with issue that has 1K log entries, but I could not reproduce any performance problems (as taking 20-40 seconds) Additionally, I will be deep diving into this next week. Thanks

Hi @Barbara Kohlroser , > Please can you gray out the "Log" Button when it has been hit? This is implemented in version 2.5.7.

Thank you @Volodymyr Krupach!

Hi @Tuncay Senturk [Snapbytes]! We have been using JIRA 6.4.12 with TTS 5.6.0 and Work Calendar 2.5.6 in production for a couple of weeks now and performance is very good! I suppose the longer response times at the beginning must have been just initial cache issues. Well done, thank you, case closed :)

Excellent. Thanks for keeping me notified.
