Primarily, it's because statement thread was started to fetch data when "cancel" was issued. I'm using unixODBC 2.2.9, psqlodbc 08.01.0102 with "Threading=0, UseDeclareFetch=1" options. Also I'm using ODBC auto_commitmode. MyLog file is attached. P.S. What I think - it's because PGAPI_FreeStmt call (from PGAPI_Cancel function) doesn't block any mutex against Fetch functions.When I tried to create special mutex to protect PGAPI_Cancel->PGAPI_FreeStmt call against SQLFetchScroll, seg.faultdisappeared. ---------------------------------------------------------------------- You can respond by visiting: http://pgfoundry.org/tracker/?func=detail&atid=538&aid=1000475&group_id=1000125
