Vlad Khorsun added a comment - 06/Sep/10 12:03 PM With great help of Dmitry Kovalenko i found following: thread 4524 doing sweep. sweep terminated abnormally because of bugcheck 179 (why it happens is another story). sweep's Attachment was released (see unwindAttach()) and its Database is releasing also. It waits in LM because there is an AST which is currently delivered. Note, Attachment is gone completely and Database almost destroyed. thread 7676 executed some query . An AST interrupted its execution. This is DatabaseSnapshot::blockingAst(). An AST established new execution context (this is almost destroyed database from thread 4524). As Attachment from thread 4524 is gone, it detached from all locks it holds at destroy time. Therefore in AST's tdbb we have Database from thread 4524 and NULL Attachment. An AST handler call PIO_get_number_of_pages() which call GetFileSize(hFile, ...) which returns error, as Database file is already closed. nt_error() call ERR_punt() and we have AV there at gds__log_status(tdbb->getAttachment()->att_filename.hasData() ? tdbb->getAttachment()->att_filename.c_str() : NULL, remember, we have NULL attachment in tdbb. This AV is loggeg in firebird.log and it is OK. But ISC_exception_post() calls exit() which is initialted engine shutdown and started to destroy all global variables and performs additional cleanup. One of the cleanup routines is INET\wsaExitHandler(). It calls WSACleanup(). Therefore we have 10093 errors in firebird.log. Listener is stopped and waiting for all worker threads to exit. But its static mutex Worker::m_mutex is destroyed and we have second AV which is a subject of this ticket.
