How to troubleshoot PVXWIN32.exe errors on MAS200 at the server. Could not write to memory. 0X00000000 Large install 25 users. 4.20.22 running as an application. Any suggestions. Also have seen at another client on 4.4.6

What version server OS?

Windows 2003 Std - 32-bit

Anything here - http://support.sagesoftwareonline.com/mas/query/index.cfm?action=abcdetail&abc_id=210

Check what @WayneSchulz linked to. If it looks good you might want to check Antivirus or any application that would monitor the system and can stop it like a firewall, etc. Is this something that happens consistently or once in a blue?

Check DEP (Data Execution Prevention)

I have 2 customers getting this. One is 12 users and one is a 25 user system.

I went back on site today to this client and I think I click through 30 pvxwin32.exe could not write to memory messages - this has been a stable client for many years - no new MAS200 patches have been applied and no one is complaining of odd messages or being booted out of MAS200. The article Wayne sent does not seem applicable in this case. I am not sure whether DEP is the issue or not.

WAG - wasn't there discussion about invalid directories or paths as a cause of stray pvxwin's on mas200?

hmm - the paths have not changed 4.2 has been on this server for at least 4 years I am thinking.

I clicked past 2 of these messages at my client yesterday. Nothing in the Event Viewer or MAS 200 system activity log. We already have it excluded from DEP.

When I have run into this before I had to disable DEP: Completely disable DEP To completely disable DEP in Windows Server 2003, perform the following with administrative credentials: 1. Open Windows Explorer 2. Tools > Folder Options > View 3. Uncheck Hide Protected operating system files (Recommended) and Hide extensions for known file types 4. Click apply > OK 5. Browse to C:\ 6. Right click on boot.ini, select properties and ensure the ""read-only"" tab is unchecked and click OK 7. Edit boot.ini 8. Modify the /noexecute= For example, set /noexecute=AlwaysOff to disasble DEP entirely 9. File > Save, close boot.ini file 10. Right click on boot.ini, select properties and ensure the ""read-only"" tab is checked and click OK 11. Reboot the computer Try doing this for a little while to see if disabling it works.
