When I attempt to restart the LISTSERV service (using Windows Services), I get "Error 1067: The process terminated unexpectedly". (Using the DOS start command, the window opens and closes so quickly I cannot see if it gives any errors.) In reviewing LISTSERV's log, I see this error: >>> Error 8 from HeapAlloc() for -453556728 bytes <<< The error occurs in the logs after LISTSERV sends out some (or all) daily nondelivery monitoring reports and immediately after it starts to rebuild the archives: ****************************************** 16 Jun 2006 04:56:05 Initialization complete. 16 Jun 2006 04:56:05 Generating daily nondelivery monitoring reports... 16 Jun 2006 04:56:05 Sent information mail to ... 16 Jun 2006 04:56:05 Rebuilding WWW archive files... >>> Error 8 from HeapAlloc() for -453556728 bytes <<< ****************************************** I received two email error messages from LSMTP about the same time we began having trouble with LISTSERV. They are basically identical: LSMTP seems to have terminated abnormally. Debugging information is included below, so please forward this message when reporting the problem. Thank you. --- 00:24:29 022FBF56 ERROR_MOD_NOT_FOUND ERROR_MOD_NOT_FOUND 00:24:29 *** Error: write access violation, PC=022FB99E, address=9400241B ***00:24:29 [SymGetModuleBase status = ERROR_MOD_NOT_FOUND] 00:24:29 022FB99E ERROR_MOD_NOT_FOUND ERROR_MOD_NOT_FOUND00:24:29 *** Error: read access violation, PC=022FB3E3, address=DC00241B *** 00:24:29 Stack traceback: 00:24:29 Address Module Symbol Source 00:24:29 -------- -------- ----------------------- ----------------------- -- [The above error is repeated several times, with different PC= and address=] 00:24:29 -------- -------- ----------------------- ----------------------- -- 00:24:29 [SymGetModuleBase status = ERROR_MOD_NOT_FOUND] 00:24:29 022F699B ERROR_MOD_NOT_FOUND ERROR_MOD_NOT_FOUND 00:24:29 [StackWalk status = ERROR_MOD_NOT_FOUND] 00:24:29 Extended thread context information: 00:24:29 thread type: outgoing SMTP 00:24:29 id: 14 00:24:29 state: 1 00:24:29 status: ERROR_INVALID_FUNCTION 00:24:29 last status: %LSMTP-S-OK 00:24:29 remote IP: 0.0.0.0 00:24:29 site: "IWRAW-AP.ORG" *************************************** Any assistance you can give in getting this service running again would be greatly appreciated.
