Dear Vlad,

before to answer you, just to say that i backup restore the database saturday, and again sunday i receive lot of :

Index 15 is corrupt on page 373097 level 0. File: ..\..\..\src\jrd\validation.cpp, line: 1538
in table TRANSAC_SEARCH_VAC_1 (309
Sun Apr 04 08:53:48 2010
Index 16 is corrupt (missing entries) in table TRANSAC_SEARCH_FS_I_2 (317)

and some
Fatal lock manager error: invalid lock id (1786136), errno: 0

but the fb_inet_server.exe look like they still answer this time. i will backup/restore the database this night again

sorry, frozen it's the best answer. the server (ie windows) work very weel, but all the fb_inet_server.exe are "blocked" (not crash, alive but they not answer to the client, like they are waiting something).. all the client are also "frozen" as they all wait answer from their queries ...

> If it was crashed - how many processes was crashed ? Do you have crash dump ?

no, sorry not a crash, no process crash, they just don't answer anything (all the process are visible in the task manager with 0 activity (read/write or cpu)

> If it was frozen - explain what do you mean. All existing attachments was frozen and no new ones are accepted ? Something else ? Does all processes have zero CPU and IO usage ?

frozen it's mean that when i open the task manager, i watch all the fb_inet_server.exe, and all these fb_inet_server.exe was with 0 activity (no CPU, no hard drive read or write). at the same time, it's seam that the engine still accept new connection (by creatting a new fb_inet_server.exe) but this new fb_inet_server.exe don't answer anything and become imedialty "frozen" like all the other

restart the whole machine. but a correctly shuntdown (Start => restart the computer). the windows system is responding perfectly, only the fb_inet_server.exe are frozen

before the bug happen and i was force to restart the computer i don't kill any actively process. i was force to kill them when the fb_inet_server don't answer anymore but at this time the index was already corrupted !

no sorry, a server "frooze" :( but frooze by zero activity in the task manager, no fb_inet_server process was doing something, they look like they wait something...
