We had this issue with SW2010 approx every 2-3 days. Now with SW2012 SP2 this issue occurs every hour. We have changed nothing else than upgraded from SW2010 SP5 to SW2012 SP2 and updated the graphicsdriver as SW recommends.
We are running XP-32Bit and Win7-64Bit. And I have to say that SW2010 and SW2012 are hanging very often on Win7-64Bit. When we use the ressource monitor from the Win7 taskmanager it tells all the time that SW is waitung for network I/O but the user has 'just clicked' some icon.
Our files are stored on a NAS attached to a microsoft small-business server 2003 with AD (I know that NAS is not officialy supportet by SW, but previusly the files where on the microsoft sbs and we had the same issues).
My thought is also the anti-virus or the firewall settings. We are using g-data antivirus software and all the SW-files and folders are excluded this is a realy long list.
still waiting for a solution (since 2010)
I wonder, is this issue not addressed by solidworks because they expect us to use SW PDM, even when we only have two users?
With regard to the inti-virus - I'm using kespersky. The -problem was cured omn one machine by switching the AV off, then genwerating some settings to exclude the SW files, but on the other machine switching thre AV off doesn't help at all.
Finally we have found the solution !!!!!
On the client side the network is configured (by microsoft) to dissconect after 15min without traffic. This is stored in the registry and can only be changed by editing the registry. please read Microsoft KB297684 carfully for details.
If you are a crack I will tell you in a short, change or add the following two reg-keys on every client computer:
You will not have any more disconnections
Plese post if this was helpfull or not for you too.
You could also set your auto-save to work at 14 minute intervals and skip the part about messing with registry entries.
i've got auto-recover, but not autosave. Been looking for it in options-document properties, but to no avail, where could autosave be located? thanks
Auto-recover is the one. But you'd need to set your recovery directory to a network drive.
An other Setting that have to be done (on Win-7 Systems) is to disable all energy saving settings in the device manager of the NIC like:
- "Engergy efficient Ethernet" = unchecked
- "Reduce link speed during standby" = unchecked
The naming is different to other NIC-manufacurers but the Windows-Standard settings are allways to save maximum energy and that is in fact to disable the network connection when not in use.
I forgot to tell about the second Setting which have to be done:
- The NIC of the workstation to be configured to disable the "Flowcontrol"
- The NIC of the server has to be configured to disable the "Flowcontrol"
- If the NIC is connected to a switch (this is usually the case). The switch has to be set "Flowcontrol" to disabled too for the used connections (On most switches this the default setting)
I have this problem too, but as a user and not an administrator, i do not have rights to change the registry and I think most people in the company won't even attempt to touch it. (i would, but am not authorised) probably like most people on this forum.
There must be a way of solving this "connection was lost trying to save..." problem, other than changing the registry.
I dont think i've had this problem with solidworks 2011.
Am using windows 7 x64 bit, with very similar specs to you Gordon.
This is driving me nuts, as all assemblies have rebuild errors, mate errors and worst of all, missing parts. *(yes as in, parts open are completely invisible and no sign of a feature tree, NOTHING.)
Has anyone else been able to solve this issue...?
