E2610: sys: 'Unalligned Access

[Rzoetekouw]

Hey, I'm having a problem with one of our switches.

It keeps on rebooting on the following message:

M 01/01/90 00:39:19 sys: 'Unalligned Access:  Virtual Addr=0x75f77622 IP=0x804c8

This error aquires around every 45 minutes.

Can someone help me fix this problem?

Was the unit actually running R.11.63 at the time of the crash or was that version loaded into flash, the unit crashed and then booted into that version?  Also, do you have any log messages prior to the incident or know if anyone or any management application was accessing the device when this occurred?
