Arcserve not terminating on NT3.51

What would cause Arcserve 6.5 with all patches applied to lock up NT 3.51?  The Backup process completes but does not release from memory.  Next time it runs it locks up the server. The only way to remove it from memory is to reboot. Important note: This only happens with Dual processors enabled. It' running on a Tricord 3000 server.  The processor boards, memory boards and backplane have been replaced.  Windows NT backup creates the same result. Good luck!

Have no experience with the Arcserver 6.5, just know SQL Server 6.5. :-))

Anyway, could you tell me some background of this problem, such as Arcserver, your NT's configuration and the network topology?


The version of Arcserve is 6.0 (Build 516) NT 3.51 (Build 1057, SP5).  The topology is Ethernet with a FDDI WAN to two other  Buildings with NT servers.  There is also a SQL server attached to the WAN among other lesser servers (mail etc.).  The Tricord NT server in question (PDC) is the same server as one on the WAN in another building (BDC) which seems to be operating fine.  I'm not sure whether dual processors are running though on the BDC. I know what I have is limited but it is being relayed to me from another source.  I will be taking a look at it personally next week to gather more info and troubleshoot.  I was just wondering if anyone else had come across this problem in the past, with dual processors.  I know Tricord has some patches out but you have to pay for them. (Ain't that nice of 'em), but I think they have been applied already.

I recommend you to install NT 3.51 SP5.


Service Pack 5 has been installed. Two or three times

Be aware that after install new application, especially third party application, Service Pack should be installed again.

More over, NT's Performance Monitor and Event View are helpful in this case. You may use Performance Monitor to trace your backup procedure.

Hope this helps.

I'm not sure about build of last service release of ArcServe 6.0.
what kind is now real? 6.5 or 6.0?

On arcserve 6.0 I've solved exact such problem on NT 4.0 SP3 with installation of last service release.

please give more informations about language installed, then i can give filenames for this release.


Heiko, English is the language installed.  It is running on a 3.51 server, not 4.0.  But it sounds like if you had the exact problems, it might help to have the filenames.  I need to ensure that the last technician to work on this server, did indeed install the NT and Arcserve service packs properly.  We have the Arcserve backup running on an "identical" Tricord server (BDC)in another building, at this time, but we would like to put the backup back on the PDC, where it was originally intended to be.
This one is on us!

I have resolved the problem myself so here's the answer for future reference.  The problem was a MAPI32.dll version conflict with the HAL.dll provided by Tricord.  The solution was to copy the original NT 3.51 MAPI32.dll to the system32 directory thus overwriting the problem dll (a version made for NT 4.0, shipped with another product) Sometimes the toughest problems have the easiest solution.
