Hi, We've been happily using OTRS 5.0.20 on Debian 8.8 for 6 month now. We've made no change at all (it's only 3 of us) to the config but last night, the program stopped fetching emails. I can still manually fetch emails going to otrs/index.pl?Action=AdminMailAccount and clicking on [Fetch mail] but it only download 10-15 at a time. The cron was set as follow (on July 20th) : Daemon::SchedulerCronTaskManager::Task###MailAccountFetch - Function = Execute - MaximumParallelInstances = 1 - Module = Kernel::System::Console::Command::Maint::PostMaster::MailAccountFetch - Schedule = * * * * * - TaskName = MailAccountFetch There is NO error message in otrs/index.pl?Action=AdminLog. I've tried the following : 1) Restart daemon > No luck sudo -u otrs /opt/otrs/bin/otrs.Daemon.pl stop sudo -u otrs /opt/otrs/bin/otrs.Daemon.pl start 2) Empty the cache > No luck sudo -u otrs /opt/otrs/bin/otrs.Console.pl Maint::Cache::Delete 3) Restart daemon and mysql and empty the cache > No luck sudo /opt/otrs/bin/Cron.sh stop otrs sudo -u otrs /opt/otrs/bin/otrs.Daemon.pl stop sudo /etc/init.d/mysql stop sudo -u otrs /opt/otrs/bin/otrs.Console.pl Maint::Cache::Delete sudo /etc/init.d/mysql start sudo /opt/otrs/bin/Cron.sh start otrs (the daemon restarted automatically after a few minutes) What else can I do?
