First line.  Your miniserv.pl allocated more memory than is allocated to
the system, so the dreaded OOM killer came into play and killed a selected
process.  Have you considered enabling swap memory?

miniserv.pl... I have webmin running yes and it was stopped after the 
restart of Asterisk...

So the bad one in this story is WebMin that was eating up all the memory ?
