.net - SQL Exception on immediate reconnect -

-

i have winform app uses linqtosql it's dal. there central sql db , each laptop has local sqlexpress db. seperate module, using merge replication, keeps 2 in sync. when connection lost central db 'fails over' local. works great.

however, when regain conection central db, if time period has not been real long, following exception -->

a transport-level error has occurred when sending request server. (provider: tcp provider, error: 0 - existing connection forcibly closed remote host.)

i have read through numerous posts here on so relating , msdn article outlines , explains, in great detail, going wrong yet, through of this, have still not found or read solution.

i wondering how others have dealt this. find hard believe treading new ground here. there way remove old connections on reconnect?

i losing hair on insight appreciated.

edit

also of note, quite positive data contexts wrapped in using , not have 'long-term' contexts.

turning off connection pooling using "pooling=false" connection string attribute seems have solved problem.

php - PHPDoc: @return void necessary? -

is necessary this: /** * ... * * @return void */ i have quite few methods don't have return value, , seems redundant put in comment. considered bad form leave out? if makes clear documentation, leave in, isn't strictly necessary. it's entirely subjective decision. personally, leave out. edit stand corrected. after little googling, wikipedia page says: @return [type description] tag should not used constructors or methods defined void return type. the phpdoc.org website says: @return datatype description @return datatype1|datatype2 description the @return tag used document return value of functions or methods. @returns alias @return support tag formats of other automatic documentors the datatype should valid php type (int, string, bool, etc), class name type of object returned, or "mixed". if want explicitly show multiple possible return types, list them pipe-delimited without spaces (e.g. "@retur...
