ASA 5550 inside interface hangs

[tuan dang]

Hi all,

Last night, the inside interface on our primary ASA seemed to "hang". It dropped all the packets it received. Because the interface didnt go down, failover didnt happen.

Device's info;

Cisco Adaptive Security Appliance Software Version 8.2(3)

Device Manager Version 6.3(3)

Hardware:   ASA5550, 4096 MB RAM, CPU Pentium 4 3000 MHz

Internal ATA Compact Flash, 256MB

BIOS Flash Firmware Hub @ 0xffe00000, 1024KB

I attached a capture picture shows that traffic didnt go to the roof when the issue happened.

Any idea why the interface would "freeze" randomly?

Thanks,

Tuan

Sorry, forgot to mention that I manually failover to secondary, reboot the primary, brought it back up and everything seems to be working fine.
