Cisco ASA 5525x Disk0 (Flash) error.

[ugabichipaopao]

Hello everyone!

Today I faced with the problem of Cisco ASA disk error.

I have version 9.4.1 image on Act/Stndb  ASA configuration. After upgrade from version 9.0.4 time to time I can't connect to ASA via ASDM.

I did short investigation and I see a probem with disk0:

ASA-Firewall# dir

Directory of disk0:/

%Error opening disk0:/ (Too many open files)
8238202880 bytes total (570736640 bytes free)

I don't see a file system

Also I cant save my configuration:

ASA-Firewall# wr
Building configuration...
Cryptochecksum: 490edde9 492ddc52 75887db8 4f73f941

%Error opening disk0:/.private/startup-config (Too many open files)
Error executing command
[FAILED]

After reboot everything is OKey. I can see filesystem and I can work with ASA. After reboot I see a files FSCK0000.REC, FSCK0001.REC, FSCK0002.REC,FSCK0003.REC,FSCK0004.REC,FSCK0005.REC

I found an articles that it can be a disk problem, but after reboot device will use FSCK utility and everything will be OKey. But, my problem repeted againe.

Please help me to solve this issue. 

Regards,

Maxim
