I have a Dell H625cdw printer recently bought new and installed on my PC with a clean install of Windows 7 64-bit (all possible Windows Updates installed). I used the most up-to-date H625cdw Software Suite and Driver from Dell support page, and also installed the most updated firmware. Printer is connected using network cable as it is too far for a USB cable. I do not print all too often, and leave the printer switched off except when needed. Since beginning use of this printer, Dell Printer Status Watcher has crashed 11 times, usually later in the evening after the PC has been on all day. A couple days ago (in the evening time, after PC had been on all day), I opened up Task Manager to check on a separate issue, and noticed that the Dell Printer Status Watcher - DLDPHSTS.exe process was using ~800MB or so of memory. I thought this was abnormal, but left it alone. Less than an hour later, Dell Printer Status Watcher crashed. I wanted to know how much memory the process uses right after booting into Windows, so I restarted my PC. I checked Task Manager right after reboot, and saw the process was only using ~15MB of memory. Last night, instead of turning the PC off like I always do, I rebooted my PC and left it on, idle, all night. I had Performance Monitor track the memory usage of the DLDPHSTS.exe process during this time. I have attached the graph of the results. DLDPHSTS.exe consumed ~400MB of memory while the printer was off and the PC otherwise idle. I am unsure why it then began to level off - as previously mentioned, I saw it get into the 800MB range the other day shortly before crashing. There is obviously something wrong with this program that needs to be patched/fixed. There can be no legitimate reason for this small background program to be consuming memory in this way. And once it crashes, you can no longer turn the printer on and use it unless you reboot PC or login out and back in to Windows, as the printer will be stuck in "Offline" status without DLDPHSTS.exe running in the background to do whatever it is it does. I have also attached images of the details showing what appears to be 2 different ways that DLDPHSTS.exe crashes - one involving the "clr.dll" file and another involving the "DLF0D002.dll" file. I would appreciate finding out when this will be looked into for a future patch to the Dell software for this printer. Thanks.
