Hi, I have an application that is using Firebird DB. After running for some time, application get stuck in following stack trace of fbclient.dll
In the dump, there are many thread that are waiting on ISC_event_wait, each with a different event. This issue happens at random and not reproducible. In some environment, this problem is more frequent and in some just one or two occurance. Most of the problem after it gives "unavailable database" error with Error Code:335544375 Stack Trace: ChildEBP RetAddr Args to Child 0142d16c 7c827b69 77e6202c 00000001 0142d1bc ntdll!KiFastSystemCallRet 0142d170 77e6202c 00000001 0142d1bc 00000000 ntdll!NtWaitForMultipleObjects+0xc 0142d218 77e62fbe 00000001 0142d25c 00000001 kernel32!WaitForMultipleObjectsEx+0x11a 0142d234 00f311e1 00000001 0142d25c 00000001 kernel32!WaitForMultipleObjects+0x18 0142d298 00f32fa6 00000001 0142d2c4 0142d2cc fbclient!ISC_event_wait+0x91 0142d2c4 00f331f0 00003a26 00000000 00f379a5 fbclient!stall+0x76 0142d2d0 00f379a5 b894c130 010decc4 00000000 fbclient!SCH_enter+0x70 0142d2f8 00f3f217 b894c02c 00000000 010deccc fbclient!subsystem_enter+0x35 0142d51c 365316a9 010deccc 00000000 0480b938 fbclient!isc_attach_database+0x87 ... ... I saw few post in this mailing list that talk about this deadlock problem but I couldn't find any solution for that. Any help is greatly appreciated.
