Thanks Mark!
But "connection rejected by remote interface" happened at 15:34, and segmentation fault happened at 15:38. It is possible that segfault has happened after?
Besides, Debian 7 Wheezy's stable package is 2.5.2, I'm not sure about to install 2.5.3 at Wheezy (2.5.3 is stable at Debian 8). Somebody has installed Firebird 2.5.3 at Wheezy?
Thanks in advance!
