Hardware interrupts

The number of hardware interrupts per second (6951) is more than the number of System Calls per second (5083).This indicates a hardware device is generating an excessive amount of hardware interrupts.

We received this on one of our accounting servers running MS-SQL server. The machine specs are as follows:

Proliant DL380 G4
Dual 3.4GHz Intel P4 HT
2048 MB RAM

There are 3 mirror pairs

Disk 0 - system disk about 75 GB
Disk 1 - SQL system, Data and Tlogs (I know..)
Disk 2 - temp db, sql backups

Anyhow, that message came from a Foglight entry so we have history of the machine to look through for troubleshooting but I haven't really found anything alarming?

Any help would be awesome.

Re: Hardware interrupts

It might also be worth while to note that we have seen this behavior on a bigger machine (Unisys ES7000) which is also running a SQL server instance.

Any help is appreciated.

Re: Hardware interrupts


Is there any abnormal behaviour in the system. Have you check the IML log for the server and use the mangement agent to monitor the useage and status of the server. It it ok and you are still considered about your server you can run the offline and online h/w daignostics from HP site for the same server.
Please share the log which you are refering to.
