Hi,
It appears that you have memory issues with one of the 3750s. I you have upgraded the IOS recently, revert back to the old one and see if the problems goes away, if not, try a different IOS version. Also open a ticket with TAC and send them the crash file.

Stay away from the version "0". Upgrade to 12.2(58)SE2 instead.
