# Connecting to a tape library through an Adaptec card with aic79xx driver might cause ESXi to fail
If your ESX/ESXi system is connected to a tape library with an Adaptec HBA (for example: AHA-39320A) that uses the aic79xx driver, you might encounter a server crash when the driver tries to access a freed memory area. Such a condition is accompanied by an error message similar to Loop 1 frame=0x4100c059f950 ip=0x418030a936d9 cr2=0x0 cr3=0x400b9000.
