Hello,

Server: FB1.53 SuperServer on Win2003 Server, default firebird.conf,
no UDF in use.
Client: ~20 simultaneous Windows clients written in C++ using native
FB API, single-thread.

1-2 times a week, firebird server is shutting down in the middle of
a day for unclear reason
with messages like "terminated abnormally (4294967295)" or "Control
services error 1061."
Please who knows what do these magic numbers mean: 4294967295 and
1061

- Windows Server 2003 and Firebird 1.53 was reinstalled from scratch;
