PCHEALTH hdmp file

Specs: Windows Server 2003
Hello friend,

On my Windows Server 2003, there is a folder PCHEALTH inside Windows folder.

Everyday, 3 files with the filename "dllhost.exe.{date}-{time}-00.hdmp" is generated on the path C:\WINDOWS\PCHEALTH\ErrorRep\UserDumps.

It's consuming huge disk space on my server. And each file is consuming about 2GB. Can you please help me, what file is this? Is this the necessary file for windows. While, I googled, I found it's a it's a error report for .exe crashes, is this true? How can I stop this file to be generated? And what will be the impact of stopping this?

Please guys help me on this. It is giving me hard time.

Thanks in advance.

.hdmp files are memory dumps created during system failures. You can stop them from being created in the system properties dialog. But that isn't a good solution. I suspect that your server is rebooting during the night because of some failure condition and these files are telling you about it. You need to find the cause of the failures.

A good place to start the diagnosis is to look in the event viewer.

Thanks LMiller,

Yeah, I have disabled the error reporting, I'll see, whether those file will be generated tomorrow or not. But I am pretty sure that system is not getting rebooted.. and those file are being created 3 times a day.. 2 times in office hour only. Actually it's an application server.

It's generating dllhost.exe related dump file whereas dllhost.exe is being used by .net framework and my application uses .net framework. So, I doubt, there must be some event in the application which is causing the dllhost.exe to be crashed... and finally getting the dmp for for that crash. The file is getting generated twice in office time only.. that means error reporting frequency is high while application usage is high... this is what I doubt.. but i m not sure whether my doubt can be a valid logic or not .. and I dont have any clue tyo check my doubt as well.. :(

Do you think, there could be something like my doubt.. If it can be a valid logic, i could talk to my application provider. Actually, we've already spoken to them and they said .. it's all windows thing.. nothing to do on their side.....

Please suggest me..
