[Opensim-users] "Save OAR" stopping since r9700

Fri May 29 18:39:46 UTC 2009

I tried with r9573 this morning to do a "save oar <oarFileName> and here is my observation:

First on ckTai which is essentially a blank region.
Region (ckTai) # save oar ckTai0529
18:16:09 - [ARCHIVER]: Writing archive for region ckTai to ckTai0529
18:16:09 - [ARCHIVER]: 0 scene objects to serialize requiring save of 0 assets
18:16:09 - [ARCHIVER]: AssetsRequest executed looking for 0 assets
18:16:09 - [ARCHIVER]: Creating archive file.  This may take some time.
18:16:09 - [ARCHIVER]: Added control file to archive.
18:16:09 - [ARCHIVER]: Added region settings to archive.
18:16:10 - [ARCHIVER]: Added terrain information to archive.
18:16:10 - [ARCHIVER]: Added scene objects to archive.
18:16:10 - [ARCHIVER]: Wrote out OpenSimulator archive for ckTai
Region (ckTai) # show version
Version: OpenSimulator Server  0.6.4.9573  (interface version 3)

Then on Europa which has pushing 1000 prims. What is interesting about Europa is that the first line (in bold) printed out immediately and then there is no response to console. The line below is 40 minutes later and there is still no console response.

Region (Europa) # save oar Europa0529
18:18:03 - [ARCHIVER]: Writing archive for region Europa to Europa0529
18:31:43 - DIAGNOSTICS

Time now is 5/29/2009 6:31:43 PM
Server has been running since Tuesday, 5/19/2009 2:31:42 AM
That is an elapsed time of 10.16:00:00.4956310

The data that we (the developers) really need is the exact revision between r9561 to r9700 on which this started 
failing.  I suggest a divide an conquer approach (see if the problem occurs on r9641, if not, then try r9670, etc.). 
Then that information should be put in a mantis (or an existing one, in which case I'll need to know the number).
