Hello: Below is an excerpt from a madExcept bug report. Does anyone have any idea why the FBClient.dll is hanging?
This is code that run many times in a session without problems. The FB DB is 2.52, superserver, local HD installed. The app is desktop app created in Delphi XE2. The DB is local to the user's HD. Thank you for any insight that might help me keep this from happening. This issue of the DB hanging on a fetch happens once in a while and very infrequently considering the number of fetches that occur during a user session with the application. Not all users experience this issue. This particular user has this the most often (a few times a month maybe) Chuck Belanger operating system : Windows 7 x64 Service Pack 1 build 7601 system language : English system up time : 12 hours 29 minutes program up time : 38 minutes 18 seconds processors : 8x Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz physical memory : 4279/8140 MB (free/total) free disk space : (C:) 162.37 GB display mode : 1920x1080, 32 bit process id : $2ac0 allocated memory : 90.75 MB executable : ProfViewer.exe exec. date/time : 2013-03-08 22:30 version : 3.0.1.51 compiled with : Delphi XE2 madExcept version : 4.0.2 callstack crc : $1448d532, $52e21aab, $5654e86b exception number : 1 exception message : The application seems to be frozen. main thread ($245c): 0851cd53 +0a3 fbclient.dll isc_dsql_fetch_m 085205ba +10a fbclient.dll isc_dsql_fetch 0073e4b5 +00d ProfViewer.exe IB_Components 31595 +3 TIB_Dataset.SysStateChanged 00733b90 +000 ProfViewer.exe IB_Components 26897 +0 TIB_Dataset.StateChanged 0072d210 +14c ProfViewer.exe IB_Components 24088 +13 TIB_Statement.API_Prepare 0072a93e +0aa ProfViewer.exe IB_Components 22997 +17 TIB_Statement.SysGetRawSQL 007468ea +02a ProfViewer.exe IB_Components 35265 +4 TIB_BDataset.SysMoveBy 00734c6a +02e ProfViewer.exe IB_Components 27335 +4 TIB_Dataset.SysJustAfterOpen 00734bf0 +0c4 ProfViewer.exe IB_Components 27314 +14 TIB_Dataset.Open 010ea67c +284 ProfViewer.exe Data 1669 +98 TDataCollection.HasChildren 0135474b +133 ProfViewer.exe uViewer 25749 +79 TMainForm.vtRegistryInitNode 00666853 +01f ProfViewer.exe VirtualTrees 22012 +2 TBaseVirtualTree.DoInitNode
