Hi,
I done in JDBC driver barrier preventing of execution of query until
the cancel will not return, but future queries after cancellation are
occasionally terminated.
The query cancel sends following 16, 123456789, pid, key, flush, after
this it tries to read EOF, I got and ignore exception "Connection reset"
- probably OK, so query cancel finishes. The next query will not be
executed until cancellation will end.
I think problem can be in backend, it can signal process but it doesn't
wait till signal is processed. I saw this on Windows 7.
If you want I can only try to attach Wireshark frames.
Kind regards,
RadosÅaw Smogura
