What does this message mean?

Fatal lock manager error: invalid lock id (46568), errno: 0

after this message in server log I found common error for all hanging of Firebird server

INET/inet_error: connect errno = 111

after this error usually server is restarted by FBGuard but previous error is new for me.

Does this message can give me a hint where to look for this regular hangings of Firebird?

Every 2, sometimes 7 days Firebird hangs, sometimes twice a day and it is not related with server load.
When I upgraded server from 2.0.4 to 2.1.3 hangings was so frequently and I must downgrade server to 2.0.5 but frequent keeps same as with 2.1.3 than I downgraded to 2.0.4 and this server version keep things bearable but problems exists as I described.

Any idea is appreciate.

Djordje Radovanovic
