Without valgrind logs, there's not much we can do. ---------------------------------------------------------------------- (0002913) tabrisnet (reporter) - 01-Sep-09 03:07 http://www.dbmail.org/mantis/view.php?id=802#c2913 ---------------------------------------------------------------------- Find said file attached. Note that the crashes don't always happen, but they do sometimes happen outside valgrind. ---------------------------------------------------------------------- (0002914) tabrisnet (reporter) - 01-Sep-09 03:29 http://www.dbmail.org/mantis/view.php?id=802#c2914 ---------------------------------------------------------------------- Worth noting that it doesn't look that bad in the trace logs I'm reading. I'm trying a different set of folders to sync, should transfer a lot more data. I have a _lot_ of email to sync... albeit at this point it's looking less and less likely that I'm going to try to use dbmail 2.3 in production (for my personal use). Still, I have enough email that I can probably keep working on debugging for a while. ---------------------------------------------------------------------- (0002915) tabrisnet (reporter) - 01-Sep-09 17:13 http://www.dbmail.org/mantis/view.php?id=802#c2915 ---------------------------------------------------------------------- Second log has actual 'definitely lost' bytes, albeit it's still measured in megabytes not gigabytes. I had to compress it as this one was 4x larger than the previous one. ---------------------------------------------------------------------- (0002916) tabrisnet (reporter) - 02-Sep-09 19:15 http://www.dbmail.org/mantis/view.php?id=802#c2916 ---------------------------------------------------------------------- This 3rd one should be more interesting. 2MB definitely lost, 100MB possibly lost, and 760MB still reachable! Total size 876MB. Large proportion of the 760 is hash table entries (from gmime). Again had to compress, as the maximum file size is 50k and this one was 60k Issue History Date Modified Username Field Change ====================================================================== 29-Aug-09 20:39 tabrisnet New Issue 31-Aug-09 09:37 paul Note Added: 0002912 31-Aug-09 09:37 paul Status new => feedback 01-Sep-09 03:05 tabrisnet File Added: dbmail-imapd.valgrind.log 01-Sep-09 03:07 tabrisnet Note Added: 0002913 01-Sep-09 03:29 tabrisnet Note Added: 0002914 01-Sep-09 17:12 tabrisnet File Added: dbmail-imapd.valgrind-2.log.bz2 01-Sep-09 17:13 tabrisnet Note Added: 0002915 02-Sep-09 19:08 tabrisnet File Added: dbmail-imapd.valgrind-3.log.bz2 02-Sep-09 19:15 tabrisnet Note Added: 0002916 ====================================================================== _______________________________________________ Dbmail-dev mailing list Dbmail-dev@dbmail.org http://mailman.fastxs.nl/cgi-bin/mailman/listinfo/dbmail-dev
