Hi all, seems that bdb people has a problem. I'll bug them for a quick solution but production will be delayed.. I'll keep you posted. alessio ______________________________________________________ Hello, The problem reported by Alessio is related to the fact that somebody created/loaded bridge collections into a slave federation. I checked this collection: /groups/skims/MasterSP/0174/R10.3.1c/01745101-01745110/Skim1046hMCObjy/P0001/KanGA/AllEvents directly in a slave federation /afs/slac/g/babar-ro/objy/databases/boot/simulation/V1/ana/0822/BaBar.BOOT oodebug print #33064-1665-1-2 BdbBridgeCollectionP #33064-1665-1-2 = { %scopeNames = { } %versioningMode = oocNoVers ooRef(BdbTreeNodeP) _node = #32768-855-3770-28 ooRef(HepExplorableDescr) expDescr = #0-0-0-0 ooRef(HepGenericTag) curTag = #0-0-0-0 ooVString _name = { ooVArray(char) _vs = "/groups/skims/MasterSP/0174/R10.3.1c/01745101-01745110/Skim1046hMCObjy/P0001/KanGA/AllEvents" } ooRef(BdbMetaDataP) _metadata = #33064-1665-1-4 ooVArray(ooRef(BdbBridgeCollItemP)) _items = { [0] #33064-1665-2-203 } } We should understand how this collection was created. I'll talk to others from bdb on what the best way to fix this is, and we will post an update soon. Jacek
