yes but that was only cause my M2 had been online for over 500 hours and the server buffers where overloaded (had not rebooted server pc in over 1000 hours)
cause the buffers where full they where unable to save when I was given a pet and therefore thought my time was up and untamed the pet
same in your case your server buffers are prob nearly full
just do a FULL reboot of the server and the server pc and all should be fine
