Summary0007083: Consistent Out of Memory crash after a few hours - even without user activity
DescriptionI'm running a standalone process with 4 regions.
regions are almost empty, very few scripts, and there is just one avatar in total.

After running for a few hours the system crashes - even with no users logged.

attached last 4 hour of log diagnostic.

looking at the log, I notice a HUGE increase in the
- InventoryWorkerThread0
- InventoryWorkerThread1

may that be the cause or it may be a memory leak or what

The Warp3d map module currently leaks memory every time it runs. You can try adding to this section in StandaloneCommonm.ini:

RefreshTime = 0

and/or in this section in OpenSim.ini:

MaptileRefresh = 0

This should disable the timers for refreshing the maptiles, but should still run once when the sim starts up. Otherwise you could switch back to the MapImageModule (in the [Map] section also) until Warp3d is fixed.

Marking this as resolved for now, Warp3d still has various other issues, but it no longer seems to leak quite so massively. Still not advisable to have maptiles regenerated all too often, please reopen if issue arises again.
