My IbExpert manager is closing very often without any error message.
Checking the FB log I can see these alerts (see below)
I can see this explanation regarding the alerts:
INET/inet_error: read errno = 10054 or 10038 or 10093

Error showings
Multiple entries in firebird.log or interbase.log with errors 10054, 10038, 10093, etc.
Reason
These errors are caused by network problems - check your hubs, network adapters, etc. It is not an Firebird/InterBase error itself, but it may impact Firebird/InterBase.
Recovery process
We offer FBScanner tool to solve "10054 errors" problem (among other issues). See details here.
Recovery chances:
Not applicable.

The strange thing here is that my FB database could be one in production or my local DB (for development). In this case the log is from my local DB.

I'm using FB 2.5, windows XP all in a virtual machine (using Virtual Box)

Diego
