We just recently ugraded from 4.2 to 4.4. After upgrade one backup task for quite big VM timeout.
Before upgrade everyting works fine. Backup took about 2-3 hours but it was ok. But now backup starts, looks fine for a moment (usually for 5-15% of backup) and then just freeze. No more progress is shown in log and after some time we ot timeout.
long freeze here
Syslog and dmesg shows nothing suspicious.
Any idea what can be cause or what we should check for more info?
