MailAccountFetch freeze

[vykook]

Hello,
I have problem with MailAccountFetch started from OTRS daemon. Sometimes( from 1 occurrence at week to several at day) job freezes for ~30 minutes and next jobs didn't start. I tried changing TTL => 60 * 60 * 24 * 3, to 60 * 5 (we are checking emails in 3 minutes period) in Kernel/System/Console/Command/Maint/Postmaster/MailAccountFetch.pm, but it didn't helped. Temporary solution is checking mailbox with external script and invoking otrs.Console.pl Maint::PostMaster::MailAccountFetch . Any ideas, where is a problem? Thanks a lot!
P.S.: output of ./otrs.Console.pl Maint::Daemon::Summary: https://pastebin.com/teNPGNGY
