Hi

I am getting the following error message in my ISA alerts every day. The word 'resource' is often ambiguous. It can mean temp file size, disk space free, logfile size, CPU or memory.

Description: ISA Server report or log summary generator reached the resource limit when generating the summary for the period: 27/10/2005 - 27/10/2005. A report generated for this date may include inaccurate information.

I have a feeling that it is the Daily Log Summary exceeding a maximum size - but that's just a guess.

We are hammering the ISA 2004 server rather with up to 1000 users going through each day. Obviously this is generating a large number of sessions and therefore logs are quite large.

The system has three logs (FWS, WEBPROXY & SMTP). As sessions go through the firewall these are logged throughout the day. I am using a W2C file with NTFS compression (as advised by Tom here). Compression is selected through the ISA checkbox in the 'Firewall Logging Properties' rather than logging to an NTFS compressed folder. I notice that this generates files up to 2,097,153KB before starting a subsequent file for the same day. We normally get about 4-5 files (8-10Gb) of logs per day.

It looks like Daily Log Summaries are generated at the same time every day (1.00am) and this data is used to generate the Daily, Weekly & Monthly Reports. I am getting the alert at about 1.18am & 1.48am each day and the final SUMD20051027.ILS Daily Log Summary file is last modified at about the same time. In all the cases the size of the Daily Log Summary is between 63,9xx & 65,0xx Mb, suggesting that it may be hitting a system max of about 64Mb. Anyone getting Daily Log Summaries greater than 64Mb?

The Daily, Weekly & Monthly reports generated from the Daily Log Summaries seem ok, but I am conecerend that they are missing information. I have set the D,W & M reports to be generated at 2.00am, therefore the error message is happening pre-Report Generation.

Any idea what 'resource' the developer is referring to? Has anyone had a similar problem or recognise the error message?

Many thanks in advance,

Chris10

I am having the same problem and am having a very hard time nailing down exactly what my issue is. Does anyone else have this problem or know how to fix it?
