Re: Windows 2003 EE DC and Domino Server hanging weekly

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

I don't have sure if will get something cause even perfmon stops monitoring during hang.

Will try it.

Thanks a lot for your time.

As it happens regularly, you could run Sysinternals Process Monitor at that time to see what is going on,

Hello,

We are experiencing a server hang always between 9 to 10AM on Mondays. Already done some actions to identify root cause but without success.

Let me explain our issue first :

For the last 1 and a half month, our server hangs. Terminal Services, file sharing, IBM Domino, Remote console (ILO2 - HP Server) and even physical console become unavailable, but still responds to ICMP. These hang events sometimes needs the server to be restarted from ILO2 or power button, in most cases it simply hangs for 5 to 15 minutes and get back to work normally without we doing anything.

__________________________________________________________
This is the environment :

HP Proliant DL380 G5
2 3GHz Xeon dual core processors
16GB physical Memory
8x146GB SAS HDs on a hardware RAID 5
HP Smart Array P400 RAID controller
LSI Adapter Ultra 320 SCSI (using StorPort) - used as interface to a Autoloader 8xUltrium2 Tape Device
QLogic Fibre Channel Adapter QL2300 1x1GB Fibre Channel interface to a Dell EMC² CX300 Storage
2x1GB onboard NC373 ethernet adapters - one to corp network, other direct attached using cat5e crossover cable to another identical server (not in use)

Windows 2003 SP2 not R2 EE x86
Not using /3GB and /PAE - early we had /PAE, but IBM Domino keep warning on low resources, then after removing /PAE it settled down
Services running : DC, DNS, DHCP, DFS domain Root and Local, IBM Domino Server (e-mail Server), some folder sharing needed on behalf our Domino Structure actually the user IDs are in theses shares to be mapped by logon scripting)
Other softwares : LTAuditor, Password Filtering, VirusScan Enterprise 8.5 patch 8
Disc and volume configuration:
8 local disks on RAID 5 - SAS: E: (local data/softare); P: (4GB of Pagefile) and C: (System)
3 LUNs on Storage - 1 FibreChannel - F: (Domino), 2 SATA - S: (Shadow Copy) and e:\usuarios (mount point holding the 607 shares of user IDs)

__________________________________________________________
Already done these actions:

Changed pagefile from drive P: to C: maintaining a minimum and maximum size of 4096MB - No results
Scheduled Tasks reviewed on local and other related servers - Nothing running at 9 to 10AM Mondays
Reviewed /PAE parameter documentation - Nothing that could do this impact found we will add this parameter on next week to test
Recheck shares and permissions on user IDs folders - Nothing wrong was found
No abnormal antivirus behavior
Disabled LTAuditor and folder/file auditing
Reviewed IBM Lotus Domino schedules, procedures, functions and logs - nothing strange
No abnormal entries on event viewer
Disabled SCOM agent
Reviewed backup schedules - Nothing running at 9 to 10AM Mondays
Reviewed all environment changes in last 3 months and nothing that could be related
Found KB 941276 talking about StorPort driver but I'm not sure if it is really applicable to our issue/configuration
Found KB 244139 and configured the manual memory dump, but could make the dump cause keyboard stops responding on hang

Any clue or direction to take will be greatly appreciated.

Thanks for your time.

ps.: Sorry by my average english :-)
