database - Still getting stuck with Mysql 2013 error after changing read time out -

-

i'm relatively new database programming , i'm hoping can me error since i'm out of ideas.

i keep getting "mysql error code 2013: lost connection mysql server during query". wrote not-short , not-simple query select statements embedded 2 or 3 levels deep in "from" clause. though can't imagine in grand scheme of queries particularly complex. when copy , paste inner queries separate tab , run them, run in under 2 seconds. when joined 1 query i'm getting 2013 error. under "duration/fetch time" field says somewhere between 50-60 seconds each time try make work.

i've read other threads , #1 recommendation increase "dbms connection read time out (in seconds):" in mysql workbench. did that. , i'm still getting problem.

i've tried in 2 different locations highly doubt there's connection issue.

any ideas?

try changing max_allowed_packet higher value.

try show global variables 'max_allowed_packet' checking current value ,

set global max_allowed_packet = <higher value>

you can set in my.ini/cnf

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
