Thanks for your detailled example.
This will corrected in next version. As a walkaround, you can set option maxAllowedPacket to 16777216.

[markddrake]

I had set it already (actually to 1G)..

Modified test case checks, and if necessary sets MAX_ALLOWED_PACKET

Hang is still observed

[rusher]

i mean something like :

    const connectionDetails = {
            host      : "yadamu-db1"
           ,user      : "root"
           ,password  : "oracle"
           ,port      : 3307
           ,database  : "mysql"
           ,multipleStatements: true
           ,typeCast:true
                   ,bigNumberStrings:true
                   ,dateStrings:true
                   ,rowsAsArray:true
, maxAllowedPacket: 16777216}

(set the right amount, 16777216 is the default example, but it must be at least that amount to solve the issue until next release, this won't have other impact and will solve the issue)

Set to 1G and it appears to work.. However with a slightly different data set I got a broken connection...

The ECONRESET appears to be Windows specific ....

Thank you already for the clear test case. I was able to reproduce it.
The exchange flows are nevertheless correct, that's interesting, need to study that in detail.

Hi, after this commit V3.3.1 I have a regression in my code resulting in Error: write ECONNRESET.
My code is inserting a batch of data.
How can I resolve this?
