An error occured while executing 'Task-DeliveryTask'

[Luket]

I got following error into ERROR_hmailserver_<DATE>.log:

"ERROR" 6380 "2018-08-16 09:51:47.946" "Severity: 3 (Medium), Code: HM4227, Source: File::ReadFile, Description: An unknown error occurred while reading file from disk."

"ERROR" 6380 "2018-08-16 09:51:48.212" "Severity: 1 (Critical), Code: HM5519, Source: StackLogger::Log, Description: An error has been detected. A mini dump has been written to C:\Program Files (x86)\hMailServer\Logs\minidump_2018-08-16 095147_{B2D0791F-D690-466D-9851-1F3A63894BA3}.dmp"

minidump is also present.
How can I fix the problem ?

Attach your Minidump to your next reply.

Probably caused by Antivirus quarantining the file while hMailserver was trying to read.

Exclude hMailserver data directory from AV scanning

Attach your Minidump to your next reply.

Wich way minidump can be read ?

[Dravion]

Minidumps can be read by WinDBG, the official Microsoft Windows Debugger. Its an Experttool for Programmers only. Its free avaiable as part of the Windows Driver Kit or the Windows SDK or as Debugging Tools for Windows Standalone Package.

Ok, the Crashdump didnt provide much infos, bc i have not the right PDB Files for your hMailServer version at hand.
I need some more infos about your hMailServer version so i can checkout and build the correct PDB's for your hMailserver.exe version which is
required for WinDBG.

Try the following:
1) Download HMSInfo.exe, goto the Downloadfolder and doubleclicl on it
2) Click the Scan Button
3) Click the Save button and give it a name
4) Attach the saved logfile to your next reply

In the meantime, disable your Antivirus tool, check your Windows Event Systemlog for NTFS, Bad blocks and Volume Error Messages
or Warnings and try again. Take a look if new Minidumps are created and Enabled full hMailServer logging in hMailServer logging Settings.

Hope this can be usefull:


Also disabling data folder from AV protection has been tested without solve the problem.

Yeah, but the HMSInfo Logfile is missing

That depends on not working SCAN function.
