Redmine

Hi!

We have more that hundred redmine users, but just one user has problem to open MyPage.

Our installed Redmine software is:

Environment:
Redmine version 2.5.2.stable
Ruby version 1.9.3-p484 (2013-11-22) [x86_64-linux]
Rails version 3.2.19
Environment production
Database adapter Mysql2
SCM:
Subversion 1.8.8
Git 1.9.1
Filesystem
Redmine plugins:
redmine_dmsf 1.4.9 stable
redmine_extended_spent_time 0.0.3
redmine_monitoring_controlling 0.1.1
redmine_reminder 0.4
timelog_timer 2.0.0

In production log I found entries about this problem and just nearby successful example of accessing same page:

Started GET "/my/page" for x.x.x.x at 2016-09-06 11:41:22 +0300

Rendered plugins/timelog_timer/app/views/timelog/_timer.html.erb (1.0ms)
Completed 200 OK in 131.3ms (Views: 110.5ms | ActiveRecord: 14.5ms)

In past we already meet once with this problem, but then we just start to use this system and can delete and restore problematic user. Currently we cannot afford to lost connection to all tasks and results to this user account.

Is there any suggestions how to deal with this problem?
