Hello,
thanks for investigation - this is only on current devel version. For
quick try, can you revert the patch and try? Practically, you have to
replace:
while( mysql_more_results(CON_CONNECTION(_h)) &&
mysql_next_result(CON_CONNECTION(_h)) > 0 ) {
with:
while( mysql_next_result( CON_CONNECTION(_h) ) > 0 ) {
two times in modules/db_mysql/km_dbase.c.
At this moment I do not have a good internet connection to be able to
investigate more and search into documentation of mysql for
mysql_more_results(). It looks like the result was not freed indeed.
Another case for such error is when a mysql connection is shared between
many processes and the access to it is not synchronized -- there were no
changes afaik that could introduce such situation.
Thanks,
Daniel

I am using stable debian so db_mysql.so linked with libmysqlclient.so.16
I read mysql doc and it is saying about this error the following:
"Commands out of sync; you can't run this command now"
http://dev.mysql.com/doc/refman/5.0/en/commands-out-of-sync.html
So this problem cause it that not freed the last result.
Only one assumption:
Could it related to this change:

Any help appreciated.
