Nokia E72 Keeps restaring when Nimbuzz 's connecting

[cslinux]

First of all sorry if i'm posting to the wrong section, but didn't find any other section that may be related to my issue.
I've got my Nokia E72 keeps restarting every 3-4 Nimbuzz's connection attempts , I'm asking if anyone got similar issue and if solved or not, I've found in some forums, that i have to restore font magnifier to default, i did and always the same issue is still happening; some other forums suggested to hard reset it, don't know if this may solve it or not .
But really I'd like to know what's the reason for such kind of issue or how to troubleshoot it.
Thanks in advance and kind regards.
