[Quickfix-developers] Re: threading growth issue? also possible crash issues....

[Alvin W. <AW...@FF...>]

I upgraded to QF 1.10.2  (Java/JNI). The crash issue got worse, 4-5 times=
=20
per day.

Another issue with 1.10, when the counterparty (acceptor) sends logon=20
message with wrong seq number, the toAdmin method is not called.=20
In addition, it seems the onLogout method is called instead, and then=20
another logon message is sent out from QF to the counterparty. As the=20
result, it becomes a deadlock. Is there a better way to handle this?

Thanks
Alvin

Maybe this sections from the 1.10.0 release notes is relevant, since the #=

Oren, perhaps you can give more details what you have changed here.
